SSH version 1.99 is merely an indication that the server supports both SSH version 2 *and* SSH version 1.
It's not really a version, as such, but an indication of backward compatibility.
See
http://en.wikipedia.org/wiki/Secure_Shell
By seting your SSH config to V2, you're disabling V1 backward compatibility (not necesarily a bad thing, given V1's well-known and documented security holes).
Cheers.
