Changing the texture data instead of "binding" a new texture is definitly not the proper way to do multitexturing, though I must admit ur approach is quite "suprising"

The correct way to do multitexturing is shown here (though in conjunction with shaders).

U simply have to bind the different textures to different texture units. It's a simple as that :)
