No. Super-relations create complexity both for the mapper and the data user.
There is no need to use them if you don't have to. In this case, the fact
that the two sections are disjoint can be found by examining the geometry:
there's therefore no need to recreate this meaning in the metadata
structure.

IME these are often handled with relation roles. For example, link routes
connecting to the main 'trunk' of a UK National Cycle Network route are
frequently added to the main relation, but with a role of 'link'.
