No it's not.

it is.

In a film camera, which is where the expression originated, a double
exposure is one exposure made on top of a prior exposure. It is not
the later combination of two separate exposures.

it definitely is. one exposure is taken later than the other, combined
on one piece of film.

as i said, it's two clicks resulting in one image.
