The extra space comes from the fact that the slopes of the top triangles are
different.  That is, the diagonal line at the top is not straight.  The red
triangle has a slope rate of 3 squares up for 8 squares right which equals a
37.5% slope, which is shallower.  The green triangle has a slope rate of 2
squares up per each 5 squares right which equals a 40% slope, which is
steeper.  The green slope is steeper than the red slope.  In the top
configuration, the top edge is concave, sagging inward.  Its left-hand side
slope on the red triangle is shallower into the sag, while the right-hand
side slope on the green triangle is steeper coming out of the sag.  In the
bottom configuration, the top edge is convex, bulging outward.  Its
left-hand side slope on the green triangle is steeper coming up over the
bulge, while the right-hand side slope is shallower coming down off the
bulge.
