Actually it is two rotations per orbit.  To people on Earth it is "horizontal" over the equator and vertical over the poles and does a full revolution over half an orbit.

A benefit is that it prevents any side from facing the sun for more than 12 minutes at a time... and also lets you plan on antenna orientation everywhere.
