That's simply a bug in the tremolo code: It counts all elements of the tremolo 
and assumes all of them are notes. So in the first case, LilyPond sees three 
events (two notes plus the staff change), assumes they are all notes and 
correspondingly adds the dot...

This problem deserves a bug report...
Can the attached (stripped-down) testcase be added to the report, too?

Codewise, the problem lies in scm/music-functions.scm, function make-repeat, 
line 281:
   (length (ly:music-property main 'elements))
instead of checking whether all elements are really notes.
