R2 mirrors R1's call
 

R2 mirrors the call and point award of R1. Which side of the court does R2 make that signal? I try to move from behind the net pole to the side getting the point so that the R1 can clearly see me and then make the signals. Some time this means making the signal after the R1 has made their signal and multiple movements. For example S serves an ace, I am on the R side when the point is made, I move to the S side make the signal, then move back to the R side for the next serve.

Doesn't matter what side you're on. If you insist on choosing one side or the other, choose the side of the team that just lost the rally, as that's where you'll need to be to start the next rally.

For some reason, it was told to us in our training that we're to stand on the side of the team that just won the rally. Any idea why there's this discrepancy? And should I just disregard the "training" advice?

I've never been told that standing on a certain side is required, but through the advice of Jan and Felix, I tend to stand on the side of the team that lost the rally if possible. As Felix stated, this puts me where I need to be for the next serve. I won't take 5 or 6 steps to get there, but if I can get there in a 2 or 3 quick steps so that my signals are mirroring the R1, then that's what I'll do. It has worked very well for me. YMMV.

Scrapper, there are a couple of reasons that we have adopted the USAV technique of attempting to get to the side of the net that lost the rally. If your partner needs a little help because of uncertainty as to who won the rally, if you are always on the side that you are sure LOST the rally, it tells your partner that the other side gets the point. The other reason is the one that Felix and Bob both have mentioned...it puts you on the side of the net that you have to be on for the next serve. One major element is avoid getting caught behind the pole! It is awfully hard to communicate with each other if you can't see each other. It is not a requirement to do so, but it is an aid to your partner in case of doubt.

Thanks for the information!
