Binding mount location

I recently bought a pair of 179cm K2 Press's and have been skeptical about their binding location. They are mounted 2cm forward, which apparently is 5cm back from the center point. When buying my skies i was told this would be good for both all mountain skiing as well as some park skiing. From experience, would this be an ok position for skiing park? Ideally it wouldn't be great for rails and such, but would it be a deal breaker? Based on this post it's pretty obvious that I'm fairly new to skiing. This was my second season and I spent most of my time doing black diamonds instead of focussing on freestyle.
