Not necessary, the for loop should work for this case.

Hmm, I guess the sorting function should not have this check. You
probably can just sort normally these ones, they will be the last ones.

And then we can do a separate pass where we check for overlapping
partitions and multiple OFFSET_CONTINUOUS.
