In fact "Without moving the mouse" is irrelevant in step 6.
All that matters is where the mouse was when you middle-clicked
in step 5.  All middle clicks subsequent to step 5 have the same
(bad) effect regardless of the mouse position, pasting the same
unintended selection each time.

I presume that having an *active* selection at step 5 makes the
difference.

More testing confirms that the initial middle click in step 5
updates the selection with the text between the start of the
active selection and the position of the middle click.
