Neri, I agree with you regarding the main points you made, therefore 
an apologize in advance, that I will come back to a comparatively 
minor point in your post.

And yet he changed his decision and hired her on the spot, to bring 
her to Hogwarts, where she was. Therefore he might not have been 
sure, if it really was a true prophecy, but at the very least, he 
considered the possibility, and therefore I assume he would do almost 
everything to keep it's content a secret from Voldemort.

Hickengruendler:

Because Snape simply disapparated? He might have been surprised by 
Aberforth catching him, and desperatly trying to hear the rest of the 
prophecy and to fight off Aberforth, did not do so at once, so that 
Dumbledore and Trelawney could see him as well. But after this he 
could have been disapparated any day. Or he simply ran away, before 
Dumbledore could do anything, and apparated from outside the pub. 
Sure, Dumbledore is strong, but he's not almighty. Bella managed to 
escape from his as well, so why not Snape?
