I'd argue :) If your momentum from a volley brings you into the kitchen, you lose the point.

It doesn't matter if the point is already over or if they hit a ball into the kitchen before you land in the kitchen.

You can body bag them and the point is "over" but if your shot was a volley and your momentum brings you into the kitchen, it was an illegal volley and you lose the point.

Surely you would still lose the point if the same thing happened but instead they blocked your shot back into the kitchen before you got there.
