The release of the swinger is the sequenced release. Uncock, then roll to get the flat left wrist in one of the 3 hinging conditions, and then mantain the vertical relationship of the flat left wrist to its associated plane until follow-through.

Concentrate on what uncocks the secondary assembly , for the swinger the centrifugal force, or wrist, forearm muscles do the uncocking.

The matter of exaggerating the "uncocking" really early in the downswing is not crucial here, and I see it as a separated component as sweep , snap release belong to a different component.
