Horny males will mate with anything and getting the right end is the least of it. It's often not even a tortoise that's the subject of the amorous advances. I have seen that happen more than once.
If it happens to be territorial bullying rather than actual mating then it doesn't actually matter anyway.
Possibly immature too. I had two males trying to breed with a female. One on each side of her LOL. The female just kept eating. Needless to say, I put them all back in their own areas.
