(scale * i for i in srcpages.xobj_box[2:]) is a generator, a single

But the value of the right-hand side /always/ is a single object!
A syntax of an assignment statement that has been simplified
by me but is sufficient for this post is:
target list = source expression
. The evaluation of the source expression yields an object.
If the target list is not a single target, that object must
be an iterable with the same number of items as there are targets
in the target list, and the items are assigned, from left to
right, to the corresponding targets.
A generator object /is/ an iterable, and, here, it apparently
yields exactly two items.
understood
It is like:
x, y = (i for i in range(2))
