Assuming the code is complete enough to be compiled, I would guess that it has no problem reading any content assets from the commercial version (even if they are packed into custom packaging files) with the major concern being versioning related (maybe the most recent source code branch references to various assets might not match up exactly with what is on disc for a specific retail build). But also it isn't that uncommon at game studios for assets to be checked in alongside the code, so I wouldn't be shocked if these source code dumps and the associated sizes being reported also include the assets.
