You are correct that you start on the receiving team's side of the net. During rallies, you are to move from side to side, staying on the blocking team's side of the net. It is much easier to see and there is much less movement if you position yourself near the scorer's table during the rally. Hugging the net support will cause you to miss more of the action than if you are back away from the play.
Don't get so hung up on moving from side to side that you miss some crucial action. If the ball is passed over the net several times quickly from one side to the other, sometmes it is best to just stay put until one side is in control or until the play ends.
The prevailing theory is that the umpire (R2 or down ref) can see a block better from the blocking team's side of the net. I don't happen to agree with that theory but that is just my opinion. I follow standard procedure and get on the blocker's side.
Regardless of where you stand, the most important thing for the R2 is to watch the action at the net. The referee (or R1) will be following the flight of the ball and it is up to the R2 to catch the net violations.
