Of course, during the first round, he will have to preempt (you) fully with 
some length in the majors, which would be "bending backwards".
The question, now, is "does there remain  some UI uncovered by AI in the 
second round ?". My answer is "yes, but marginal" (i.e. you don't hold the 
pure Acol hand of AKQxxx and two outside tricks), so that it will seldom be 
relevant ... but it might, especially in slam bidding.

BTW, we had the same concern with Gilles, and the solution seems to be that 
one should wait a little before doing any two-way opening, any version.
