In the event of a log plex failure the volume remains online. Logging a mirrored volume is optional. So, its failure would not affect the State of the volume.
As to the comment included when storage1 fails, that the log tracks regions to be resynced, I don't believe this is correct. A plex failure will require a complete resync when it is brought back online. The DRL bitmap is referenced after a system crash to limit what needs to be copied between plexes.
