That's difficult to tell without a peek at the repository.

Did you compare 'gitk HEAD' to 'gitk HEAD -- WRITING'? I'd expect the
latter to be a subset of the former. Note that with a path specified
"history simplification" happens, which means that you won't see as many
merges as when no path is specified.
