I have seen multiple accounts how homosexuality is selected for. Similarly how ant queens have many non-producing drones whose existence is not a superflous extra, if you have some non-reproducing members in your family they can be an asset rather than a drag. You can be a fulltime uncle which is less possible if you need to be a full time father too. The non-reproductive sex can be a force to have social relations more strongly in place like how that role is more pronouced in bonobos.
if you are the 7th sibling then that is only 1/3rd of child per sibling parent. The effect of “33% more likely per sibling” which I didn’t previously know about fits in. If you end up having only very few families, risk that all of them do not reproduce by chance gets more significant. Upkeep of a “dubiously useful” extra person gets amortized better the more families there are.
Brothers doing wars tend to be somewhat even and thus continue for a long time. With 4 children, starting 4 lineages with 2 parents leads to more factions than 2 lineages with 3 parents. Or any other effect where increasing the number of families becomes blocked it then makes sense to make the “allowed families” to be more robust. Maybe on hitting starvation shanking the uncle leads to less infigting (sacrificial hierachy instead of lottery) and does not produce orphans.
But I don’t actually know. But seems there are things that actually need checking.

Each child given up by being homosexual would have to be compensated for by two children had by one’s siblings. This doesn’t sound plausible to me.
