Yup, seems so:

"A right-handed user can access, in order of increasing difficulty, and
starting with the point already mentioned:

   a. The pixel immediately at the current cursor location: Click the
mouse and you're done.

   b. The bottom-right corner.
   c. The top-left corner.
   d. The top-right corner.
   e. The bottom-left corner. "

However, it also depends on the angle at which user's hand is actually
holding the mouse. Usually, people are at a desk and have the mouse
right next to the keyboard, and the above would be fine. 
But if the user's hand is not at that angle, then angle of ease for
movement would vary.
