Takes control means it takes the substitute away from the opponent and uses it as your own. They can't make another one until the one from before is destroyed. Now a different pokemon on the opponent's team could make one(but not the same pokemon, even if they switched out and came back in, because you still have THAT pokemon's particular substitute) and if you already have a substitute out on your side, stolen or created, this move will fail if used, obviously. If you baton pass the stolen substitute, it will still act as if the sub was stolen on whoever you pass to.
For example:
You have Mismagius vs whimsicott. Whimsicott uses substitute, and you use Puppeteer. Her sub is "stolen" from her and is used for Mismagius now, leaving whimsicott not only open, but unable to create another sub since she already has one on the field. Now if she destroys said sub then she'll be able to make another one, but until then she's subless, even if she switches out and switches back in, as long as that stolen sub remains on the field. Knocking whimsicott out won't remove the sub either, it has to be destroyed, or mismagius would have to switch out, which erases the stolen sub like it would any other.
Hopefully it's clear now, yeah my previous description was a bit vague.
