In one word: high performance.  Well all right, two!

One carb for each cylinder can flow more air than one carb for
all cylinders.  Plus you can jet them differently for each cylinder,
which is useful on air-cooled multi's that can't cool all cylinders
evenly.  Ducati V-twin's have one cylinder in front of the other and
the rear always runs hotter.

Of course, balancing and jetting are problems.  The Honda 250cc 6
cylinder racing bike (RC-166?) of the late sixties had six carbs!
They changed jetting by swapping the complete set!

There are exceptions.  The Benelli 6's (750 and 900) have 3
two-barrel carbs, and the new Suzuki 550E's have 2 two-barrels.
