2013 FED Interps

[zm1283]

SITUATION 9: With runners on first base and third base, the pitcher legally steps toward third and feints a throw. With his pivot still engaged with the pitching plate, the pitcher turns and feints a throw to first base. RULING: This is a balk. While engaged with the pitcher’s plate, the pitcher may not feint toward first base. The runner from first is awarded second base and the runner from third is awarded home. (6-2-4a)

When was this changed? I thought the difference in OBR/NCAA and FED was that in FED you didn't have to disengage on the 3rd to 1st move? This says that FED is the same as OBR/NCAA.
