Odd, that isn't how it behaves on my Droid. The reduced header becomes visible as soon as the top of the full header gets under where the reduced header will be (so that it covers information which it replicates), well before any message text gets to that area of the screen. The most I can get it to obscure is the top half of the "To" address and the date that is on the same line. I tried altering my animation level, but can't reproduce the bug you mention.
