I tripped up on this part as well. I've been using colemak for many years, and I don't enter "the" the way described. When your hands rest on the home row, you left pointer finger is already on "T" and your right middle is on "E." To enter "The" you only need to move your left pinkie 1 cm to the left-shift key and your right pointer 1 cm left to "H". It's so little movement you can just about smash all four keys at once.
