Yep, that's exactly what I meant. You can create a bigger file but it 
doesn't use any more of it. However, if you change the PageOverCommit var.
to a value > 4, you change the Max. Recommended Size and can get even
bigger swapfiles.

As for the reason that the default value is 4, you would have to ask the 
MS gods. My personal guess would be that they rolled a dice. :)
