Since both software and the hardware interface can command an E-stop, the hal file asks the interface to come out of E-stop, but then doesn't check the current result until the next servo cycle, to give the hardware time to actually complete the task. If the hal code didn't wait a cycle, it would always find the interface in the E-stop condition, and you couldn't get out of E-stop.
