My understanding of SP ASA Fly Ball mechanics is as follows:

If in the situation given previously, we have a runner on 2nd and the batter hits a fly ball to Center Field, I as the BU will button hook inside the diamond, as I have responsibility for the batter-runner touching first. I also am responsible for him all the way to third base, being that the batter-runner is the trailing runner. I'm not looking to see if the ball is caught. That's the PU responsibility. He's got the catch and the tag.

Is there a problem with my understanding?

In our association, we use verbal communication. The PU will usually say "I've got the tag at 2nd". If there are multiple runners on, say 2nd and 3rd, then the PU will say "I've got the tag at 3rd", the BU will normally respond "I've got the tag at 2nd". In this situation, if the ball is not caught the BU has to quickly turn to first to make sure the batter-runner touched first.

How do you communicating to the BU that the runner can leave? For example, what happens when the ball is touched by the outfielder but not caught? If I'm watching the runner at 2nd, I need to know when he can leave. The PU should indicate as soon as the ball is touched that the runner can leave, whether the ball was caught or not. Should you say something like "Let'm go!"?
