If it's true about the 'Move' option for triple battles(possibly doubles as well?), it'd help some strategies.
For example: You have Gyarados, Electivire, and Staraptor on your side. On the other side, your opponent has Jolteon, Blastoise, and Ursaring. You predict your opponent will of course use an electric move on one of your two electric-vulnerable Pokemon, Gyarados or Staraptor. You want to utilize this opportunity to boost Electivire's speed with Motor Drive. You know your opponent most likely will predict this and attack the least likely Pokemon you'd choose, of course this is up to the trainer battling currently. The Pokemon least likely to be attacked would probably be Staraptor, so you'd switch Electivire with Staraptor to that spot, and in turn, let Jolteon's electric move boost Electivire's speed.
I'm assuming that moving a Pokemon to another Pokemon's spot would use that turn up for them, not letting them attack.
