RFC 5009 section 8: The P-Early- Media header field includes one or more direction parameters where each has one of the values: "sendrecv", "sendonly", "recvonly", or "inactive", following the convention used for Session Description Protocol (SDP) [7][8] stream directionality. Each parameter applies, in order, to the media lines in the corresponding SDP messages establishing session media. Unrecognized parameters SHALL be silently discarded. Non-direction parameters are ignored for purposes of early media authorization. If there are more direction parameters than media lines, the excess SHALL be silently discarded. If there are fewer direction parameters than media lines, the value of the last direction parameter SHALL apply to all remaining media lines. So the answer is "Yes. Direction specification is given for 4 m= lines of the SDP."
