This is the most reasonable explanation I've read with regard to Snape
and Dumbledore's relationship and the UV.

I keep coming back to Dumbledore's pleading on the tower.  As many
have argued, for Dumbledore to plead for his life, at such a cost and
after all the speeches he has made about not fearing death, would
undermine his character and make him a bigger fraud than Trelawney.

And yet, for Dumbledore to be pleading with Snape to kill him as part
of some hard and fast plan seems a little too grotesque.

I believe it is as you say, that both men have had time to thoroughly
familiarize themselves with multiple possible outcomes and
contingencies upon those outcomes.

When Snape arrives that night on the tower, the outcome is determined.
 Both of them know what is going to happen.  When Dumbledore says,
"Severus ... please", I think it is not in reference to what is
occuring on the tower, but to some other promise Dumbledore has
extracted from Snape.  Something Dumbledore wants Snape to do even
after he is dead.  Maybe it is the same thing they argued over in the
forest. Perhaps it is to look out for Harry.
