In the instructions I think there is an error. It highlights ‘F’ halfway green and in next step it turns out that letter should be ‘E’. Isn’t F subset of E except for missing bottom horizontal piece? Why isn’t the whole F highlighted as green.

First guess only shows the top line match. Second guess shows the two top lines match. And so it goes.
