It's so he doesn't die to minions attacks immeadiatly when his ulti dies giving him the oppertunity to press his heal. Because you know, it'd be unfair to expect him to get out of his ultimate with some hp left or use his heal half a second earlier...

Seriously though, that is the reason, and although it makes some sense it's a bit silly given what his ultimate already does.
