So it is indeed. But you underestimate the cunning of ESE!Lupin. 
He was indeed transformed, but thanks to the potion  he had a 
human mind and, as we learn in OOP,  a convenient view of the 
Quidditch pitch from the DADA office. It's interesting that despite 
people summoning dementors hither and yon through the last 
three books, we have no idea how it's done. If it's a mind trick, 
then  transformed Lupin could do it, provided he's had his potion.

It's interesting that the other time dementors invade the grounds 
in PoA, Lupin is also transformed.  Of course he's supposed to 
have forgotten to take his potion then, but Snape's been wrong 
before.
