You don't think it would be reasonable to say something to the effect 
that the order in which non-deterministic expressions are evaluated is 
non-deterministic (ie implementation-defined)? Certainly it would be 
reasonable enough in the case of a random number generator.  Although I 
suppose if you are going to seed it, you would like the seed to effect 
the random numbers that are generated.
