Line of apsides question

In an eccentric orbit, the line of apsides (an imaginary line that runs
through the major axis) rotates in the direction of travel for the
satellite, particularly when the orbit is of low inclination (due to the
equatorial bulge of the Earth).  The rotation reverses when the angle of
inclination exceeds 63.4d.  My question is - why is this so?  I can't
figure it out.
