Is there any particular reason that this multistep construction is preferable? It seems we can draw both horizontal and vertical lines simultaneously and Then p is just a weighted sum of a,b,c,d where the weight is proportional to the area of the rectangle with diagonal cp,dp,ap,bp.
(This was how it was covered in CS194)

These two constructions are equivalent, I don't think this construction is specifically preferable for any reason. https://en.wikipedia.org/wiki/Bilinear_interpolation#Weighted_mean
