I work for a company that transports bikes all over the country. Its all we do...
It is a normal practice to pivot a bike on its stand, not only by us, but the manufacturers too, in fact it was a Harley employee that taught me how to do it, we use this technique on everything from scooters up to 450kg Harleys
We don't sit on the bike while it is being moved like this, because its a lot easier to balance the bike on the stand and your leg at the same time
I will say that some bikes are not capable of doing this, but that's usually because they are built to a very small budget and cost about $1000 ride away
