It allows you to be a FI in SEPs for anything which isn't for intial license issue.
So you could do check rides, 1 hour with instructor flights, Any retraining for anyone working up for a test after being out of 2 year check. Instructor for people out of 90day check for pax carrying. People coming back from the US and needing local instruction before going solo etc etc
here is the on track web listing for it

edit to add yes.
And i can put you in touch with someone who has done the course with them. And alos i believe the course hours etc will go towards a full FI if in the future they drop the CPL theory side of things. And it looks pretty easy to maintain as well. None of this flogging round the country going to seminars and the like.
And another bonus is that when ever you go places with another pilot 2 people will be able to log the hours. And alos most plane insurance will cover instructors flying them as well as the named pilots.
