I had a Simpson Classic 1 synthetic that was like that. I attributed it to too short a loft. I've removed the knot from the handle and will soon install a Muhle Silvertp Fiber V2 knot with a taller loft. What are the loft and diameter of your knot?
Greetings
Whilst I have no personal knowledge of the brush in question I do own quite a few latest generation synthetics and I would make the following observations:-
Whilst the tips may be super soft the actual shaft of each fibre is stiffer than most if not all natural hair brushes so in order to get a reasonable amount of flex into a synthetic knot the loft does need to be taller than a natural knot.
Natural hairs individual hairs do absorb water to a greater or lesser extent thus they become more pliable after a soaking whereas synthetic fibres are waterproof so remain just about the same wet or dry.
Taking the glue bump into account as you rightly say the effective loft is IMHO as short as hell!
Plissoft type knots vary a great deal from one supplier to the another, some knots have thinner individual fibres than others and these sorts splay much easier, also some are denser than others and more dense knots are stiffer.
Taking into account all of these points your brush is (IMHO) a stubby stiff little bugger because the loft is too short for the diameter and type of fibre, in fact I would suggest that it is too short for any type of synthetic fibre and arguably too short even if it was a badger.

Norfolkdick summed it up very well. I should have mentioned that the knot of my Simpson Classic 1 synthetic measures 22 mm X 41 mm, which is similar to your knot taking into account the glue bump. I found this brush totally unusable. On the other hand, the knot of my other synthetic, a Muhle, measures 21 mm X 52 mm, which makes for a much more pleasant and effective lathering experience. I must say, however, that notwithstanding the performance of my Muhle synthetic, I am not a convert to synthetic knots. I use my Muhle just for travel as it dries very quickly and works well enough. I'll take my badgers (of all grades including pure) and boars over a synthetic any day. The only natural hair that I prefer my Muhle synthetic to is horse hair.
I think you've hit the nail on the head - glue bumpGreetings

Was going to make a thread about synthetics and springiness. My last purchase was a Kent Infinity and I find it hard to splay on the face for lathering. The knot stays together at the point like a painter's brush when twisted between fingertips. Not entirely short loft either at 52mm.
Is this just a characteristic of synthetics? Do they have a break in at all?
The good news is, that the Yaqi representative replied to me and it is a known problem with earlier production batches. Since i also told him that i will make a 3rd order, he told me that when i decide to do it, they will send me an extra brush as gift.
I bought the same brush for my dad, I will try it out to see if it has the same issues for splay.
Good, it will be interesting to see if this is just happening with some brushes or it is universal problem. With mine, you can feel the glue bump with your fingers, if you press at the base of the knot. That's how i measured it. It's like it has a cement wall at the base of the knot.
BTW, the representative, told me that the newer batches that have this problem solved, are the Sagrada, the Ferrari and the Mysterious Space brushes.
The glue bump of 22mm/52mm Yaqi Plissoft is rock solid at the base of the brush like it is with my larger 24mm/57mm Yaqi Plissoft, in comparison the glue bump of my 24mm Omega S Brush doesn't as significant a glue bump feel at the base of the brush - which does not want to splay at all, just springs off.
I did a quick trial lather with the 22mm/52mm Yaqi Plissoft and had no problem getting the brush to splay which was the same for the 24mm/57mm Yaqi Plissoft for today's shave.
I'll use the smaller brush for tomorrow's shave and report back whether I have any problems with it.
