Now, the way I see it this is one loooong foreshadow.
Nobody really trusts Snape apart from Dumbledore which means he probably made some kind of master-plan right in the beginning, long before Harry Potter gets to Hogwarts and Severus Snape is going to be one of the main keys to destroying Voldemort.
Either he is an unwitting decoy of some sort, or he is really (for some reason) 100% loyal to Dumbledore and killing him is part of the plan.
Remember that Dumbledore is called the "Greatest Wizard of All Times", he might have made an elaborate counter-spell that causes the Deadly Curse that Snape directs at him to trigger a deathlike sleep, maybe even something that puts him into some kind of "immortal Stasis" where nothing physical can harm him.
The point of this would be this:
Snape regains the full trust of Voldemort AND Voldemort sees his most dangerous foe gone and decides to openly take action thus revealing himself to his enemies in full for the first time and making it possible for Harry Potter and his friends (with guidance from a strange source that later turns out to be Dumbledore) to find and defeat Voldemort.

This trust from Dumbledore towards Snape looks similar to Jesus' towards Judas. It's all an accessory to a goal, definitely part of the next plot.
Draco will be solicited to enter the Deatheaters and perform a ceremonial deed; again part of folklore.
