Don't know if it's only in Holland that way, however PU has the catch and the runner in one view. So that way it's PU's responsebility.
A catch by F7 with R1 on 1st leaves R1 for BU; a runner at 3rth with a catch by F7 gives the runner again to PU.
We let the positions of the catch and the runner(s) on the base(s) dictate us who has which runner. Catch is always for PU and the runner(s) in the straight line of view to the catch. The other runner(s) is/are for BU...

It's difficult for new bees, but if you're (a little) experienced easy.
