\partcombine runs and creates a common score. Since none of the tags is
removed, the result contains both c4 and c'4. This is stored in \note.
I don't remember: doesn't partcombine complain when given parts of
different length?

Here you put three instances in a row.

The \music has already been partcombined, so there are no traces of any
tags left any more. \keepWithTag doesn't do a thing on music without
tags.

Basically, you need to use the equivalent of \keepWithTag/\removeWithTag
_before_ running \partcombine. Afterwards, you only have a combined
list of events without any tags left.
It would be nice if \partcombine were rewritten to run just-in-time.
The current implementation runs it when encountered, however. Which
means that it also has no access to context properties and other
niceties.
