Something weird happening with stampede reversal

So I go into practice mode as Grodd vs Grodd and set the dummy to reversal stampede. I then stampede and alternating holding either back or down.

Most of the time, the dummy will hit me with his reversal (as he should be able to, seeing as stampede is minus 14 and has an 11 frame startup). However, sometimes I'll be able to block his reversal by holding back, and very rarely I'll be able to block his reversal by holding down.

What is going on here? I've messed with the spacing, it still seems to be random. My inputs show exactly stampede, and then either down or back. Anyone have ideas? Maybe something with training mode?
