This is a good catch by the way, and itself another oddity.
Canon Dumbledore told Harry a lot about Voldemort’s background (including the Riddle years and his theories about the horcruxes) - HPMOR Dumbledore has done none of this. And yet he expects Harry to fight him, and Harry already knows about the prophecy.
Another issue is that I’m recently doubting whether Quirrell/Voldemort is actually Tom Riddle in the HPMOR universe. It is clearly implied that Quirrell = Voldemort, but then suddenly in chapters 84 and 85 we get this Quirrell = Hero identification (from a Noble and Ancient House, no less). Further, Eliezer has made it clear that Hero is not Tom Riddle (by adjusting the birth year).
So what are the possibilities? It seems that either Tom Riddle killed the original Hero character, and then impersonated him in the fight against his alter ego Voldemort. Or, even more intriguingly, the Hero character fought and defeated Tom Riddle much earlier on, then set up the Voldemort character to be the awful Dark Lord with a “secret” identity of Tom Riddle, while himself being the “secret within a secret” identity, and the heroic adversary. This is a plot worthy of a truly evil Sith Lord such as Emperor Palpatine. Presumably the Death Eaters as well as Dumbledore and aurors are all deceived, and this is the real reason why booby-trapping the grave of Tom Riddle’s father (after TSPE) is going to be of no use. Quirrelmort has no need to hide the father’s grave, because it’s totally irrelevant.
