That is a good point, and one I hadn't thought of.  But I always assumed
that the reason it makes a difference in dilution is if you are supposed
to put 8 ounces of water and then add 1 "spoonful" (the spoon provided),
you get just that when measuring water first, because you measure
everything correctly with the bottle.  However, if you put in the one
"spoonful" first, it takes up volume in the bottle.  Depending on the
size the spoonful is, it might be 1/2 an ounce, or 1 ounce in itself. 
Just watch the water level go up as you add the formula (or chocolate
powder, if you try this with some thing that is actually DRINKABLE at
home!  LOL), to 8.5 or 9 oz total in the bottle.  So, if you put the
powder in the bottom and then add water to the 8 oz level (which is what
most people will do) then the formula will be too concentrated, because
it ends up being 8 oz of liquid with as much powder in it as was
supposed to go into 8.5 or 9 ounces perhaps.  One could, if one had any
brain cells in their head at all, get around this easily, by measuring
the liquid *before* pouring it into the bottle, in another measuring
cup.  You measure 8 ounces into a measuring cup, put the formula powder
in the bottom of the bottle, and then add the already measured water to
this bottle.  This keeps you from using the bottle's graduated marks to
figure out how much water you're putting in, and then becomes more
exact.  HOWEVER, it doesn't take into account Barbara's point about the
way it mixes up differently (not as well).
