What sort of paint is the black stuff? oil/water based?
Not sure, it's Ultra Black as at:

Well, did the instructions say to clean your brush in water or turps?
Whether it's oil- or water-based might help with deciding how to proceed...

They didn't say. However I can report that the foam applicator for the
black paint gets clean under a running tap.

Is there any way I can find out?
How recently was the redecorating done - do you have any of the mocha
stuff left over?
Very, and I sure do.
...howewver, the above being the case, I'd say your solution is a
no-brainer, just paint over it. As the decorating is recent, and you
have more paint from the same batch, there shouldn't be any evidence of
a junction between the old and the new... if they are chunky dry drips
of black paint then you'd want to sand them flat first, otherwise
they'll still show through. And try to 'feather' the edge of the area
you paint rather than make a definite edge - will help make it less visible.

A no-brainer is just what I'm looking for. I've already sanded some of
the black off, I took my time, and I managed to disturb minimal good
paint. I was careful (for me) - I started with 400 grit, but it took
ages, and I was unimpressed. The 40 grit shifted it. I suppose the
medium grades are more for when you sand the paint without removing it
all!

The idea with any sanding work is to start with the coarsest grade you
need, and then to work up (down?) through the grades until you get to
the desired level of finish.

Out of interest, what difference would oil or water have made in the
other case?

Well TBH probably not a hell of a lot once the paint was completely dry
and cured; I was just looking for more info at the outset and if you
hadn't had the right paint in stock it might have been worth trying
something using the appropriate solvent?
