In theory it can be correct because of smaller tree after inferior QxQ but I think that in this case the right solution is to be more aggresive in reductions after PxN and not to search the inferior move first.
QXQ is _always_ the best move when the capturing queen is undefended. You cannot try PxN before, otherwise you lose your queen.
This was exactly the reason that I expected QxQ(see=0) to be the best move more often than PxN.
My intuition clearly told me that the case that the queen is hanging may happen often but Bob told me that my intuition is wrong and PxN is usually better than QxQ(see=0) so I continue the discussion based on his assumption that is that PxN is better in most cases and the cases when the queen is hanging are relatively rare.
