I think the point the UK CAA is pointing out here is that an applicant for an ATPL(H) checkride needs to hold a MP type rating BEFORE he can do the ATPL(H) checkride.
That was the "old" regulations under JAR, and this is also taken over into CAP804...
So in your case you would have to attend a multi pilot helicopter type rating course (which is (afair) 10 hours for your first MPH rating), and THEN do the ATPL(H) checkride (which can be combined with a type rating checkride, but NOT with the initial MPH type rating)..
