As of Max 7.3.2, seq supports MIDI Type 1, so a non-zero int argument (as a single argument, or following a filename argument) to the 'write' message will cause the seq object to write a MIDI file in format 1 with separate tracks.
Otherwise, seq always merges all tracks into one and always saves as format 1 and this is the behaviour Cyclone has.
