Marauder's Map Folly?

CH3ed:
I have been wondering about why Lupin didn't see 2 Harry and 
Hermione when he looked at the Map in PoA also. It does seem to me 
that the Map covers most of Hogwarts ground, including the Forest 
(tho I'm not sure about the interior of Hagrid's hut). The bits of 
canon I recall supporting the Forest being on the map come in GoF 
when Harry asked the fake Moody if he had used the Map in his search 
for the then missing Mr. Crouch. The fake Moody, IIRC, said he did 
by taking a leaf out of Harry's book (summoning it from his office). 
This bit may or may not be true (as the fake Moody was probably 
eager to make Harry trust him, and that could be an embellish story 
to compliment Harry), but it is backed up by his confession under 
the influence of veritaserum later that he had used the map to 
monitor the ground for Mr. Crouch after recieving a message from LV 
that Crouch had escaped, and that he did spot his father entering 
the ground on the map. 

So my best explanation is that either time-travellers don't show up 
on the map, or that they do show, but it was luck of the draw that 
Lupin noticed the real time Harry and Hermione first, and he 
concentrated on them so much he didn't notice another Harry and 
Hermione in the vinicity. 

CH3ed hoping he hadn't goofed on his recollection. Just moved to 
California and the books are in still in the boxes. :O)
