Halftime positions?

[rfp]

I can't locate this. The positions for the R and the U in the 15 min. before the game are clearly described: R in front of the home bench watching the visitors warm-up and the U in front of the visitor bench watching the home team warm-up. When returning to the floor at half-time, do the R and U stay in front of the same benches (and watch the opposite team warm-up) or move to the opposite sides and stay with the same team they saw before the game started?
