One-armed entry for sasae-tsurikomi-ashi

From Monday's training diary entry:

If you're fighting for grips, and your opponent snags your lapel, you can reach around behind to take a grip on his far shoulder. This puts you in a cross-grip (ie, same-side lapel) position, and it will fold his arm and keep it tight. Feint as though you're trying to snag his free arm with your hand. If he pulls back (which he probably will), step across, facing him, hook his armpit with your elbow in a rising, lifting motion, pull his lapel-side arm across and around, and block his lapel-side foot with yours in a classic sasae move.

Easier to show than to describe, no?
