Well, even though it has a similar name it does a different kind of thing than the BooleanMerge command.

BooleanMerge will intersect surfaces with one another and extract all volumes that are produced.

The other Merge command is about merging 2 edges that touch one another into a single edge.

They do different things so they are different commands.
