I'm not totally sure, but from what I've read it seems like all software extensions were resolved in software. That is, it never passes _extra_ remaining depth to the hardware because of extensions in the software. That would probably mean a lot of extra times where the hardware can't finish its search fast enough (remember, they limited a single hardware search to 8000 nodes), and has to pass back to the software for more plies, then it would get split back to the hardware again with less depth.
