Yes when you put a round 3D surface image onto a flat 2D camera image, it doesn't fit. The said they eliminated a lot of the errors but not all:

Thats a possebility, in 2nd video there's a obvious failed alignment.edit on 8-10-2011 by Mimir because: (no reason given)
The feature isn't too far from the edge of the image, and it abruptly ends at the ends of the image. A real feature would be unlikely to end exactly where the image ends. It's not impossible, but it's more than a coincidence if it does that at BOTH ends, the odds of that probably ARE close to impossible.
Note that some distortion of the shaded relief base was introduced when it was warped to the CLCN; this distortion is pronounced in some areas at 1:1 million-scale. The CLCN (and therefore the Clementine mosaic and related products, including the base images used for these maps) was later found to have large horizontal errors, on average of about 7 km, and in some areas perhaps as great as 20 km. Those errors have been largely corrected with the Unified Lunar Control Network (ULCN) 2005 (Archinal et al., 2006), on which the Lunar Orbiter global mosaic is based (Becker et al., 2005, 2008).
Note that because the two sets of maps use different control, the locations of the features are slightly shifted, and features near or on the edges of maps might fall within different quadrangles.
