The obvious one is whether .el is newer than .elc. I also thought it was something to do with the documentation lookup. In fact on my Debian system, looks like they use symlinks to link the source .el into the directory with the version-specific .elc. Probably to avoid those very problems that come from separating the .el and .elc. But hey, patches welcome if someone wants to address this long-standed, complicated issue.
