You cannot deny that the particular wording in 6.5 is clumsy and can be interpreted in different ways. A more clear wording should have been used.
It is possible, because of unclear english, to interpret this clause to mean that the MUST (strictly) applies only to the encoding and not the use of ;binary in both the request and response.
That is one possible interpretation. I will suggest another in a following email.
