The quarterback in this formation is not in position to receive the snap. ASCII art (letter diagrams) cannot show this fine a detail, but a quarterback in position to take a handed snap is allowed by rule to stand farther forward, in a place which would otherwise cause illegal confusion as to whether the player was in the backfield or the line. However, the popularity of thrown-snap formations from about 1920 to about 1950 (and the illegality of the handed snap in Canadian football when snapping by hand rather than foot was first prescribed in that game) induced some teams to place the quarterback a little farther back, receiving the snap via a short toss.
