Enough hours have passed:
Allowing the borders of the square does NOT matter. The likelihood of one of the endpoints falling in any given area within the permissible bounds is proportional to the area. The lines at the edge of the square have length but zero area, so even if they're allowed, the selected point will "never" be on the edge. A bit more formally, the chances of a point on an edge being chosen is infinitesimally small and (excepting something massively discontinuous like a delta function) does not affect the integration over the area.
