That's nonsense.
R3 would add around 240K ATMs per year to the existing 480K capacity. That equates to around 650 daily movements.
The night quota operates for 6½ hours, from 23:30 to 06:00, so that would require 100 movements per hour.
Apart from the fact that LHR can't sustain anything like 100 movements/hour, how many routes do you seriously think would support arrivals or departures in the middle of the night?
