Yeah - this is a pretty high end set of gear to mess up.
Remember that the value of the goofed up skis does not go to zero. They can likely get roughly what they paid for the skis by ebay-ing them with the holes... So if they actually goofed by a 1 or 1.5 cm they should do the swap & get it right ---- or give you an option of some other make-good commensurate with both the reduced value of the skis and the hassle and expense you have to go through running back and forth.
There are so many screwed up mounts out there it makes my head spin. No one is perfect, but it is worth supporting shops that know what they are doing & get it right well over 99% of the time... For me, that's usually Gerk's locally in Redmond and www.untracked.com
for the remote stuff. I'm a fan of the guy who I think is still running the shop at Evo too, but that's just a PITA for me driving wise for day to day stuff. So worth it to know the odds of getting the job done right are high and the odds of any possible error being fairly dealt with are pretty much certain.
