You're getting pixel aspect ratio (PAR) and frame aspect ratios mixed up:

640x480
720x480
720x486
720x576
768x576

Are all 4:3 (1.33:1) Frame aspect ratio

All have non-square pixel aspect ratios except 640x480 and 768x576 which have square pixels.

(N.B. 720x480 & 720x576 can also be 16:9 Anamorphic)

You crop the 640x480 with the same amounts as the 720x480
