Can you think of a case of actual retroactive preemption? 

Preemption is negative causality (Is it not?), and a cause must 
precede its effect. But not all assertions of temporal precedence 
entail causality. Post hoc sed non propter hoc. But "before" is used 
in both cases.

I think "before" gets the hypothesized "preemption" meaning as an 
important special case of temporal precedence--causality--and is 
essentially a matter of emphasis in English usage, and the ambiguity 
must be resolved from context. English is not yacc-able. Similarly, 
I suspect "B follows from A," which can be a purely logical 
relationship, is derived from metaphor based on temporal sequence, 
suggesting causality, which is easily conflated with the concept of 
implication in English usage and Volkgeist.

Of course, a quick check of the OED might lay all this to rest. Wish 
I had one handy.
