Question about comment field for keys

The manual page for ssh-keygen says:
 
"For RSA1 keys, there is also a comment field in the key file this is only for convenience to the user to help identify the key."
 
It seems though that RSA2 and DSA keys also have comment fields, not just RSA1.  Is this just an error in the documentation?
 
Also the documentation says that only RSA1 key comments can be changed with ssh-keygen's -c option and this appears to be the case.  Is there a reason for this?
 
I just want to verify my impression that all types of keys have comment fields(regardless of what the man page says) that can be initialized to different comments when the key is created but the comment can only be modified for RSA1 keys.
