GID 128... that's the SSH preprocessor... SID 4 is the ssh protocol mismatch 
alert... the rule in preprocessor.rules shows the classification as 

alert ( msg: "SSH_EVENT_PROTOMISMATCH"; sid: 4; gid: 128; rev: 1; metadata: 
rule-type preproc, service ssh ; classtype:non-standard-protocol;)

"non-standard-protocol" is listed in the classification.conf as a type 2 event...

we don't use unified output over here so we can't help much further other than 
to say that your research so far is confirmed by what we see over here...
