It sounds more like he had just started to roll

... and got hot brakes?
What's LH's policy on aborted takeoffs? Do they require a mandatory brake inspection after any aborted takeoff, no matter what speed they attain? Do they have a minimum amount of time allowed before another takeoff attempt on a heavy? That might explain their actions after the incident.

I recall an incident years ago with a Wardair 747. They started the takeoff roll for an intercontinental flight, but aborted after some warnings came on. They then taxied to the gate for a quick maintenance fix, and then taxied to the runway for a second attempt. A number of tires blew on the second takeoff roll.

The investigation determined that because of a steady tailwind and slight downgrade to the departure runway, the crew had to ride the brakes while taxiing. The combination of two downhill trips to the active runway, plus the aborted takeoff was enough to overheat the brakes, even though the aircraft spent 30 to 45 minutes at the gate for the maintenance check. They changed their brake check procedures and extended cool-down times on heavies after that incident.
