Fair or Foul?

[Jerry]

A FAIR BALL . . . is on or over fair territory when bounding to the outfield past first or third base.

A FOUL BALL . . . is on or over foul territory when bounding to the outfield past first or third base.

What possible major controversey could erupt from that? Perhaps a disagreement on whether it actually bounded on or over the bag? That's a judgment call then. The definition itself is pretty basic.
