Remounting bindings in the same holes isn't a problem at all. I wouldn't worry about it. If they have to drill new ones, theoretically it weakens the integrity of the ski, but in practice the only thing it effects is the aesthetics.
I've been looking at PE and NY Gully when I've was ski touring up in the area last couple weekends. Looked like they were in good nick. Lots of other ice and mixed shit to climb up there too right now.
