It can also mean that they chose not to include VRAM coolers because it is  
cheaper that way. Whether they are necessary or not depends on many  
factors outside the control of video card designers. Also, simply having a  
cooler is not the same as having an effective cooler.

It can change the temperature, but not radically, unless you are talking  
about the video card casing. In any event I doubt you could get an  
accurate temperature reading using only your fingertip under any  
circumstances. The point of the exercise is simply to get a feel for how  
hot those things get.
