Dealer powershifted my car to diagnose and replicate a transmission issue..

I have an intermittent issue with the SRM sometimes going into 5th gear (never any grinds though) so I took it to the dealer. Sure enough they couldn't replicate the issue. I spoke with the tech who test drove it and he said that he tried various things to replicate the issue but couldn't, including power shifting. I got a little mad when he said that because isn't power shifting bad for the transmission? My car isn't grinding now or ever did but is it possible that what he did accelerated transmission wear or does it need to be done a lot to have any ill effect?

The car drives perfectly even after, no grinds or crunches or anything like that but I'm still a little worried he might have done some damage. I never power shift so I don't expect others to with my car as well.
