How unique are waypoint names supposed to be?
The names are not globally unique and when entering the plan into the FMC, the crew should check the leg distance.  They are sufficiently far enough that the crew will see 1,812 miles instead of 135 miles. 

Many FMCs will also only offer "sensible" choices and a deliberate action is required to select a "nonsensical" waypoint.

Often, a mistake in choosing the wrong waypoint will also alert them with a "not enough fuel" message, or an obvious gross error such as a total distance of 3,323 miles instead of the 756 miles expected.
