You mean you play a pivot (FH from the backhand side), then crossover to wide FH and fail to recover?
There is a thing about 3-point FH, Falkenberg and other drills that include a pivot. Although you can see pros doing them a lot, they are sort of pointless. For example, it makes no sense to play more than a single iteration of the Falkenberg. Why? In a game, if you play a pivot, you have to hit hard to win the point outright, because it will be difficult to get to the next shot. In case you don't win with the pivot, you may have the second chance and make a crossover. If you didn't win by this time, you are done. At best you will end up fishing some 10 feet away from the table. So if you want to train pivot and crossover, go ahead and practice them, but not in a continuous pattern, because it will never happen in a game.
When pros do these drills, they usually "cheat" by moving into position ahead of time so that they will not have to crossover. There is some utility to this training, but not much, at least for us.
For example, in the video below FZD is playing 3pt FH, but he does not cross over his legs.
