Bogus frame flex "test?"

I know the subject of frame flex has been discussed ad infinitum in
this group, but I wanted to throw out this recent observation. On a
recent visit to a LBS, the owner took great pains to demonstrate for me
how flexible my current ride is by - you guessed it - squeezing the
brake and then pressing on the pedal. Low and behold, the BB appeared
to deflect sideways quite a ways. Here's the thing, though. When I
actually RIDE the bike, I never get any front der. rub, even on the
hardest out-of-saddle climbs with the der. trimmed close to the chain,
and I've never had any unintended rear der. shifts or hihg-speed
shimmy either. In short, this frame works perfectly for me (plus,
unlike the new frame the LBS guy wanted to sell me, this one is bought
and paid for!). So my question is, what's actually flexing during
the frame flex "test" described above? I suspect it's mostly the
tires.
