As far as I can tell, the H2A crap is redone using the H4 engine, but there has been some talk of it being an early version of what they're using for H5 (but that just sounds like added technical and QA pressure, so if anything it's a modified H4 setup). Either way, IDK if the behavior will still be there, but I believe they have posted videos of matches on the H2A maps so you can see for yourself.
