The annotation by user RocknRollArchivist (not a forum member, sadly) says “second version”, which implies that there may be a difference in composition for the medley? If you are familiar with the song’s, perhaps this medley has a unique bridge or something like that?
Unfortunately the link in the annotation is dead as well, and no Wayback Machine archive. Probably something to ask them in the edit notes before merging/splitting.
The yellow highlight (SPOT DUPLICATE RECORDINGS userscript) indicates that there are 2+ relations to the same recording and work, which is usually a mistake coming from recording merges.
