Hmm, I use "npostavs" as my nick on freenode, and I get 
 
    09:43 -NickServ- You are now identified for npostavs.

Maybe the difference is that you are registering with the capitalized
version, but then authenticating with lowercase?

For reference, it looks like ERC also uses case-sensitive comparison
(see erc-nickserv-identification-autodetect and erc-nickserv-alist).
