No it doesn't. It *defines* ">" as the only quote character, when using this format. If you are using format=flowed then you must quote with ">". If not then you can quote with anything you like (although naturally if you use something other than ">" then you have chosen unwisely). If you are generating format=flowed and quoting a received mail that wasn't in this format then you can either quote them verbatim (with ">" characters) and let the reader work it out, or try to convert their text to format=flowed (the latter might be frowned upon by pedants; the former by format purists).
