Update : I was curious and did another test, but this time clicking not the act but the "infinite' button next to it. (that I also never used until now). Repeating your 6 steps, it indeed creates 2 loops, I get:
"owner fucks slave 1 in missionary position [interrupt]
"slave2 fucks slave 3 in missionary position [interrupt]
And in that case clicking pass indeed raises arousal for all 4, however only slave 2 and 3 will orgasm, owner and 1 will stay at max. I think that's what you meant, and that's probably a bug indeed, as all 4 should orgasm when reaching max.
I went back and saw your screenshot on the previous page, confirms it, you have to set up loops using "infinite mode" and only the last pairing will orgasm.
I think I'll simply ignore that Pass button and those infinite symbols as I was doing before.
It's easier to set owner to give, slave 1-2-3 to take, and just keep clicking "fuck in turns" if you just want the mana.

"slave2 fucks slave 3 in missionary position [interrupt]
