So perhaps he planned for her to sort-of die in there, but then when he thought about the timelord DNA thing, he forgot about that...
(e.g. if she's got one heart and not two, maybe a timelord needs two hearts to be able to regenerate -- one of the hearts takes over while the other's working, I dunno.)
