Piston bug! wrong update mechanism - BUD

The update mechanism of pistons are broken since 13w09b. I tested an elevator design from 1.4.7 in all snapshots and now its broken. The design was based on a perfect timing and logic. In the Video I show you the Problem exactly. I think the reason is the changed updating mechanism of pistons. The BUD-powered Sticky fires first, not the normal piston. And thats the bug. Actually the directly powered normal piston should fire first! ... please fix this!
