Probably the same model (I believe it originated as the 1701-D in the "theses are the voyages" sequence from the end of ST Enterprise), but that might just be what a circa 2399 Galaxy Class looks like. So we can't quite call it an error yet. I believe there's a painted up 1/1400 AMT 1701-D and 1701-E somewhere in Picard's chateau. They showed them off with other props a few months back (SDCC?). EDIT: Yup. And both of the kids were done extremely well. They even fixed up Ten Forward to be late season accurate.
