There is a healthy amount of overlap in a sequenced release. You have to start rolling well before impact(at which point the left wrist is level). Since there is still an angle well less than 180 degs between the left forearm and shaft when the left wrist is level with any normal grip, and even less still at the point that the roll starts, you're rolling a big bat(the whole club), not a little one(the clubhead).

Don't forget though, how important the right arm is here.

Bucket - that is the key here.

Tiger has moved the 'closing' to the right place, from a timed left wrist flip (which only works well by CF), to the straightening right arm and pivot throw out.
