Because A has just not the same value in both terms of the equation. In the left it means "the lowest" and in the other "the highest".
It's two versions of the reality in the same equation, which is wrong.
Use 100 usd / 200 usd instead of A and 2A and you'll see. If you never switch and if you always switch in both case the equation is
100×0.5 + 200x0.5
