Sorting something like a bus route ensures that the various ways that
constitute it are connected
nose-to-tail.  This is what "ensures the members are connected" and ensures
they are connected
in a sensible fashion.  Sorta.  It may not do a good job if the route
traverses the same way in the
same direction more than once.

I've noted with dismay the lack of debugging support for relations. For

Nope, it's not just you.  I too have problems getting my head around JOSM.
I use it when I have to,
to merge or split areas (such as when I find out that a large forest that
somebody else mapped
has two named chunks).  It's probable I find it hard to use because I don't
use it enough, which means
I don't use it much, which means...  But I also have to admit that I find
Java programs in general are
not a good fit with how my mind expects things to work and they all give me
a steeper learning curve
than non-Java programs.  Which means I try not to use them much, which
means...
