You can force one layer to be in front of the other, but it won’t be exactly in the middle like that.
The solution is to duplicate your comp so that you have two identical comps. Hide the red layer in one comp and hide the green layer in the other comp. Then pop them both into a main comp and use the Linear Wipe effect to reveal the lower one.
