The patent being asserted by Sewell and his crew is USPTO Patent #1,042,012, first granted to the American Mathematical Society in October 1912, subsequently renewed, then acquired by Apple at an unknown date.

The first entry among the patent's Claims describes "A quadrilateral having all four interior angles of 90°, opposite sides that are parallel, and congruent diagonals that bisect each other."

Yes, Apple is asserting a patent on the rectangle.
