That's so cool! Well, I have used that format for line 365296 cause in that
case the stops are the same node, placed on the way for both directions,
cause it's a tramway, and I would have to insert them twice in the relation,
right?, while in the other cases, the bus stops are placed off the way and a
single node corresponds to a single bus stop. But as it works in both cases,
then i think we shouldn't worry...

It's probably useful to consider as lines with branches lines with same
route_ref and, for example, considering the tag state=alternate (and
hopefully, same operator=) and then let the script check whenever the ways
and nodes are differing.
Yes, this should be perfectly possible.
Then I noticed that on some lines, if I tagged the terminus only with role
"stop" it doesn't show the terminus or shows it only on one direction.
Should I include twice the terminus in the relation?
And, do you think you could add the option to show also the lines stopping
at the same given stop (and eventually symbols for nearby park + ride or
