Shrug.  If you want to change the tie direction for the voice crossing,
you can use

\temporary\slurUp ... \undo\slurUp

Slur direction does not consult other voices, so a voice crossing is not
detected automatically.  And usually the slurs need to go outside in
order to not make a mess.  So the default makes sense usually.
