Spacing discrepency between simulator and game with Falke trial 10 combo

With Falke versus a cornered opponent, it seems like you end up with more separation/pushback in game than in the simulator if you try her tenth trial. The beginning of Falke's trial 10 goes like this:

8HP, 2HP xx CS_S xx VT1, 3HK, 5MP

The simulation delays the 8HP as long as possible. The demonstration in game hits it pretty high. People say that you need to both hit it high and microwalk after the VT1 to get the 5MP to link without whiffing. The simulation shows the 5MP hitting no matter how high the 8HP hits and with no microwalking, but as far as I can tell, this does whiff in game.

Bonus bug: the script for 3HK seems to be called 6HK (https://sfvsim.com/diff/FLK/000/moves/3HK.html)
