PointResize is also known as Nearest Neighbour.

There is no interpolation it chooses the value of the closest geographical pixel.

For YV12, if pixel 1 is red and pixel 3 is green, what colour will pixel 2 be? Let's assume Green, now crop off 1 pixel, pixel 2 becomes pixel 1, 4 becomes 3, etc. Oops we just shifted the chroma ....
