I set the exit_hint only on exits directly from motorways because hints 
on parallel lines should be created from the destination tags.

So have a look on the following junction:

===E====================================
     \                              /
      -------e----------------------
              \
               \destination=Berlin

=== motorway
--- motorway_link
E   exit node on motorway
e   exit node on motorway_link

So and exit_hint is created only for E because after you have passed E 
the Garmin should tell you the correct destination which is usually 
written on the signs in the motorway junction (in Germany...).
If an exit hint would also be created for e you would see the 
destination only after passing e and that's too late.
The motorway junctions if have analyzed did have the same tags on E and 
e so there is no additional information.
