What is the rationale of jump in contigs.paths?

[Martin-lc]

Hi there, I have a question:

metaSPAdes has output 'contigs.paths' which contains the path of segments connected either by links (denoted by a comma between segments) or by jumps (denoted by a semicolon between segments).

My understanding is that jump is something you use to put multiple contigs on a scaffold and the contigs connect to each other on the scaffold via jump.

So I expect jumps in 'scaffolds.paths', but why are there jumps in 'contigs.paths' as well, which should represent solely contigs?
