For my own curiosity, how do you get into this situation, and what does
it mean to have multiple stage#1 entries for the same path? What would
"git cat-file :1:path" output?

That is how we natively (read: not with the funky "virtual" stuff
merge-recursive does) express a merge with multiple merge bases.
You also should be able to read this in the way how "git merge" invokes
merge strategies (one or more bases, double-dash and then current
HEAD and the other branches). I think there are some tests in 3way
merge tests that checks what should happen when our HEAD matches
one of the stage #1 while their branch matches a different one of the
stage #1, too.
