Do we know what the other emergency was? All the reporting I've seen has been very vague on this.
United aircraft did a high speed abort (80+ knots) and afterwards, fumes from hot brakes were entering the back of the cabin. (Not uncommon.)

Unrelated United aborted takeoff, as well as reported some odors in the cabin from the flight attendants.
