The countable in this case is that you only ever do the 25 hrs of teaching and learning once no matter how many instructor ratings you do.
And there's a lot of credit going from ME to SE. You only need 15 hrs in class and 1 hr of flight under supervision of an FI or CRI qualified in class. The instructor teaching you doesn't need to have the privilege to teach instructors weirdly
