This is a great drill - lift the inside ski at the end of the turn and start the new turn on the old outside ski (which will become the new inside ski):
There are several variations.
The old "white pass lean" is where you lean the upper body into the new turn, so more inclination than angulation or flexion.
A modern Weighted release where you flex to release but still maintain weight on the old outside ski and transition that way.
Also switching the weight to the new outside ski, can happen late in the new turn, which is started on the old outside ski (new inside) aka the "white pass lean" or the more modern style: switch before the fall line.
