The only thing he denied is having blackouts, which may or may not involve passing out but either way involves loss of memory over a long stretch of time while intoxicated.
He said he sometimes drank too much.
He said he sometimes did things he wasn’t proud of, but never engaged in sexual assault of any kind.
I highly doubt any of his roommates are really contradicting this. What we have here, I’m sure, is the politically motivated roommates mischaracterizing his testimony as him claiming that he never or very infrequently drank excessively (something he didn’t say, since even “sometimes” is a very subjective term covering a broad range of behaviors) - and then saying that their observations of him show that this is a lie. It isn’t, it’s them turning it into a lie by claiming the judge said something that he did not.
