Prince of Persia (PS3) - skipping black gate at Coronation Hall

Third of the four black gates skipped. However, as usual you seem to need both power plates to be able to reach the boss. And in this case, you need to have the yellow power to have Prince auto-target the plate during the extended jump. The trick used here is that if you keep R1 pressed while running down a ledge like this, you are able to jump to any direction you want for a short period of time.
