If the bridge is not centered on the top and yet the strings are equalized on the fretboard,that means the neck is not set perfectly in-line with the centerline of the guitar. The bridge location on the top and the way the strings set on the fretboard are a function of the relationship between the neck and the top of the guitar, nothing to do with the tailpiece. But... The tailpiece seems to be located in-line with the neck, so the strings lie across the bridge evenly, so it's possible that godin installs the tailpiece based on the set of the neck. It's purely a visual thing, no impact on tone in the least. I'd do some more measuring - since that guitar has a veneer top with no center line it's possible the top itself is a little off center, so the F-holes are what's a bit off, not the bridge location.

When I do a neck set when building a guitar, an awful lot of the work is ensuring that the neck is straight on the body. I use special straight edges to reference the center of the top, the joint between the two sides of the solid wood top. In fact, a great deal of care is taken throughout the body build process to ensure that the centerline of the guitar is maintained on the top, the joint between the two side rims, and the back. The f-holes are located very carefully so they are centered as well. When the neck is on and the bridge finally is installed, it's centered on the top as well. It's a function of how well the guitar is built.
