The system can't perfectly predict if you are going to upshift or downshift so the engineers designed it to always bleep when you go into neutral. Don't believe me? try it. I think they did this to make downshift bleeps even faster/smoother. It may have actually be done to work around a heavier flywheel...its a pre-bleep to the real downshift bleep, like a jump start. Maybe the flywheel is so heavy that if they didnt use the pre-bleep, then it wouldn't feel as quick.
I think the lighter flywheel will make the pre-bleep even more noticeable. However, it will help the system overall...

Makes sense... In fact I wrote a similar explanation on my srm track thread a while back, here: syncro rev match where I wrote:

I have no data to confirm that SRM would hold the revs higher when up-shifting but it makes some sense. imagine you are accelerating and in the next second you will go from 55 to 60 in 2nd, as that's happening, you press the clutch and start moving the shift lever... SRM sense that you are 'passing the gate' for second gear and b/c you are now going 60 as you 'pass the gate' out of the gear it momentarily thinks you may be going into that gear and ups the revs... then you're on your way to 3rd and SRM targets a lower RPM but the damage was done...

...an 'electronic gate' that is located at the entry/exit point of every gear... if so, with srm on, we're going to hit that gate even when going out of gear on an upshift
