What you are describing sounds exactly like the preamble to mating. The male will grasp the female by the scruff with his teeth and hold her - then with his back feet, try to "kick-start" her (looks just like he is trying to start a motorcycle) so she will assume the appropriate position. The "backing up" you mentioned puts him in the appropriate position.
My guess is that this young male isn't neutered ... and if I am correct, you should do so immediately. Does he also spray yet? If he doesn't spray now but isn't neutered, it is only a matter of time before he will spray.
If he was recently neutered, the hormones which tell him to act this way are still running through his system. It can take a few weeks for them to go away after being neutered.
If he has been neutered longer than a couple of weeks, then my guess is this is dominance behavior.
