1 base or 2 bases?

[ctblu40]

From OBR-

8.01
(e) If the pitcher removes his pivot foot from contact with the pitcher’s plate by stepping backward with that foot, he thereby becomes an infielder and if he makes a wild throw from that position, it shall be considered the same as a wild throw by any other infielder.
Rule 8.01(e) Comment: The pitcher, while off the rubber, may throw to any base. If he makes a wild throw, such throw is the throw of an infielder and what follows is governed by the rules covering a ball thrown by a fielder.

So if he doesn't step backward with the pivot foot, he's still "in contact"
1 Base.
