I'm saying he did something different. If I had to hazard a guess, Epsilon was already rampant and unstable so he likely did the same thing that Cortana did when she died.

Frankly I'm not even entirely sure how he even functions and how deleting his own memory could leave the memories of the other fragments and Alpha when he IS their memory. Epsilon didn't even have a form of his own, he used the memories of Alpha for his base form, though because he remembered more than Alpha originally did and had the memories of the other fragments as well, his personality was slightly different..

That said, he reasonably should only be able to manifest himself as a single one of the fragments or Alpha at a time but on a few occasions he took on more than one, which has to be a strain on his processing power and likely shortens his lifespan. Fact of the mater is, when he died, he was probably at the end of his rope to begin with.
