So I have to get more down - and therefore uncocked in the followthru... I think.. That means that the level condition at impact/fix is an uncocking wrist still in movement downward?

yes and yes (at impact). I think a good setup to get the feel would be a plane board dug into a fluffy sand bunker: one could slowly rehearse the feel of maintaining the sweetspot on plane past the ball, into the sand to low point and still uncocking to follow through.
