Huh! I wonder what hp-lexicon is basing that on. I generally trust them as very thorough, but if that's based, for example, only on the statement that Sirius was 16 at the time, then that's not really enough proof, because he easily could have been 16 for the second half or so of his 5th year...
I suppose Snape's memories might not be chronological, but all the rest of them do seem to be in order... Also, as stereolightning pointed out above, Lily and Snape's friendship ended completely when he called her a Mudblood (in the worst memory, at the end of 5th year), so that conversation where they're talking as friends and discuss the prank that happened "the other night" has to have come before the worst memory.
...Which, darn it, I totally agree, character development-wise, I want it to be in 6th year, too! But it looks like the evidence in favor of 5th year is pretty strong.
Then again, JKR is notoriously bad at keeping her math straight, so maybe we should feel free to interpret it as we like. ;-)
