There is no difference in MESS or MAME. Most likely for MAME another check/fix missing lookup found the set.

The mentioned option is disabled by default and this is good. Fix missing does several things. If a rom is identified as missing (i.e. not a simple rename within the rompaths), clrmampro looks

a) in other sets by a quick database hash compare
b) in the backup folder
c) in the addpaths

b and c is done using a quick lookup by setname, parentsetname, clone setnames.

If you got the set in an addpath but with not a correct name, it won't be picked up. The reason for this is simple: speed. If you need a quick way to add it, use the rebuilder. It's the prefered method to add sets to existing collections.
