Certainly I agree that nobody executes all of UML -- for one thing it's too 
vast and much of the semantics are underspecified. 

I don't understand what you're saying -- it seems to me that your description 
of UML compilation is generic enough to apply to compilation in general.

The link was merely (an attempt at) a tongue-in-cheek example of the fact that 
it is possible to generate an executable system directly from UML. A subset of 
UML with its own extended semantics, but UML nonetheless.
