I think you read "resize a frame" and "set the size of a frame" as
referring to the same operation.  But they aren't: the former is about
changing the size of an existing frame with a mouse or with
set-frame-size, whereas the latter is about doing other things that
implicitly require the frame's size to have pixel resolution.

So no, this is not repetition, and should not be removed.
