HIV is fairly fragile, but given the right environment it can stay active for a long time.  Unfortunately the rectum is a pretty perfect environment for HIV to thrive.  If a guy takes a poz load, it will be infectious in him until it’s gone, IE, cleared out by a bowel movement. If the bottom is on PrEP, the virus is unable to reproduce, and will just be cleared out. If they are not, and the bottom becomes infected, it would start reproducing in them, and they would become infectious to others in approx 1-2 weeks.  The caveat here is if the top is undetectable. The virus cannot become more virulent without infecting the receiver, so an undetectable is still very low to no risk because there is almost no virus present, and not enough to infect the bottom or another top.
