If you think of the structure of the square planar molecule, the lone pairs lie 180 degrees apart at the bottom and top of the structure and the four bonded atoms are in the equatorial plane in the form of a square. Generally a lone pair will distort the angles between the bonded atoms, however because a square planar has two lone pairs on each side of the equatorial plane, the distortions sort of cancel each other, resulting in just 90 degrees between the bonded atoms.
Although there are line pros present in the regions of electron density, the angles will still be at 90°. This is because the positions of the lone pairs are on opposite sides to keep the molecule balanced, thus the lone pairs cancel out.
