For the record: the MIDI file player and the MIDI sequencer are two
different interfaces of FluidSynth. They are implemented independently,
though the player could be reworked to use the sequencer as a backend
(some day). But anyway, both functions need to play MIDI events on
schedule.
Where is the MIDI sequencer interface used? It looks like something
that belongs to the Jack MIDI server.
fluidXtra, by Antoine Schmitt is using this interface

fluidXtra is listed in our applications page
http://fluidsynth.resonance.org/trac/wiki/Applications
there was a thread on January about this matter

About your question: yes, Jack MIDI provides some sequencer functionality, but
it requires Jack audio daemon running, because it uses the Jack audio buffers
sample count for timing. Another available MIDI sequencer for Linux is the
ALSA Sequencer. There are some more sequencer engines for Linux and other
platforms.
Having a platform independent sequencer integrated in FluidSynth has obvious
advantages. It is a decision of the application developers to use it, or
something else.
