It is possible that during a refresh something goes wrong and snapd decides it should rollback. To simulate this we should have a test as part of the upgrade suite that would do a refresh to the new revision.
This test will downgrade the snap through the channels, and at each downgrade, attempt a rollback.
Example of downgrading while rolling back through channels:
Channels: 1.32-classic/stable, 1.31-classic/stable
Segment 1: 1.32-classic/stable -> 1.31-classic/stable -> 1.32-classic/stable
Segment 2: 1.31-classic/stable -> 1.30-classic/stable -> 1.31-classic/stable
