multiple texture texture lookup

Hi, all.
when I use multiple texures, (the texures are in different size, and they are mapped properly to the same geometry). If I try to access the texture on fragment shader with call texture2D(texture1, vec2(s, t)), texture2D(texture2, vec2(s, t)), texture2D(texture3, vec2(s, t)). can they get the color for the same geometry point?

tks
