Multiple header fields with the same field name - unwritten assumption about quoted commas in values?

Hi!

In http://trac.tools.ietf.org/html/draft-ietf-httpbis-p1-messaging-21#section-3.2
one reads

"Multiple header fields with the same field name MUST NOT be sent in a
 message unless the entire field value for that header field is
 defined as a comma-separated list [i.e., #(values)]."

Is the unwritten assumption that each value out of "values" has no
unquoted comma?
