"Go get your invisibility cloak"

Hi, all.  I just finished rereading the HP books for about the zillionth 
time, and I woke up during the night the other night thinking about 
something that I wanted to throw out for discussion/consideration.

In the beginning of HBP, Dumbledore tells Harry he wants him to keep his 
invisibility cloak with him at all times, and Harry seems to be doing this, 
judging by all the times he puts it on to investigate Malfoy.  But on the 
day when Dumbledore takes Harry with him, Dumbledore asks Harry to go get 
his invisibility cloak and meet him in the entrance hall.  And it appears 
that Harry already had the cloak with him, because all he got when he went 
back to the dormitory was the potion and the map to give to Ron and 
Hermione.  So why would Dumbledore ask Harry to go get something he'd 
already been told to keep with him, and which he apparently had with him 
anyway?  Was there something else going on behind the scenes, or in 
Dumbledore's mind, that we don't know about?  I also noticed that Dumbledore 
was looking out the window when Harry came to his office that day, and 
continued to look out the window at the end of their conversation before 
Harry left, to supposedly get the cloak.  Dumbledore seems to me to be 
watching or waiting for something.  I just think there was more going on 
than we know about yet during that time.  What do you all think?
