You're not wrong.

No, that would be extremely confusing.  But I think something like
this has been suggested before (I don't remember by whom):

    ${parameter-word}
    ${parameter:-word}
            Use Default Values.  [...]
    ${parameter=word}
    ${parameter:=word}
            Assign Default Values.  [...]
    ${parameter?word}
    ${parameter:?word}
            Display Error if Null or Unset.  [...]
    ${parameter+word}
    ${parameter:+word}
            Use Alternate Value.  [...]

I don't know.  It seems like boldface is used to highlight the parts
that are unique to each form.
