That's just trading one word for another! OK, how do you force the audience member to pick a specific card from a deck?
> An example of equivocation can be as follows: A performer deals two cards on a table and ask a spectator to select one. If the spectator chooses the card on the left, the performer will hand the card to the spectator. If they pick the card on the right, the performer will take that card as his own and have the other card be the spectator's. In either case, the spectator receives the intended card.
Or maybe you're asking more precisely exactly which forcing mechanism would be used, for the trick in TFA?
1. Get them to tell you to stop as you flip through the cards vertically, and then sleight the card from the bottom of the deck instead.
2. A simple counting trick like this https://youtu.be/ekPbMhJGYmc
