Ah, I see. If the events of End of Time are referenced so, the identification does seem to make sense. One wonders if the punishment was for originally going along with Rassilon's Final Sanction, or for betraying him at the last moment and allowing the Doctor to ruin his plans…

(Oh, and if you were wondering, my addition of the "According to one account" language… it's because… I mean, we don't have a straight in-universe account, sure. But the implication is very strong that she's the Doctor's mother. And certain accounts of the Doctor's mother certainly don't square with this info.)
