IMHO, the system should never automatically change an attribute from a
specific to a more general value -- to do so is effectively throwing
away information.  The track segment should keep its association; the
user can manually change it if desired.

To be honest I don't think it really matters, as long as it behaves in a
consistent manner.  I would suggest inheriting the netname of the first
connected track and marking a short with the second.
