Is there a reason why picking among the choices in a sliding window
must be contents neutral?

I see these "illogical" (== stylistically not matching user intent) diffs
quite often.  C comments (as in the example given) and #ifdef blocks
are typical cases.

Purely anecdotically, I have seen more trouble applying "illogical"
diffs than I would have expected from the corresponding "logical" diffs.
