5S does not ask for QH because the 5H response has denied it. And even if 5S did ask for QH, it forces you to slam anyway, so a 6H response would mean "no, I still don't have it, so let's go down in 6H". Note that there is an ace missing on this hand in addition to QH.

I have made many posts in this thread about not bidding a grand at matchpoints unless you can count to 13 tricks, for exactly the reasons you give.
