This is because there is a large number of transatlantic flights leaving around 13.00 so 11.00 to 11.30 is prime time for departing passengers clearing immigration.
Anybody passing through at around 12.40 will likely miss their flight (as I did due to late inbound flight from VLC).
I also noticed that they have recently installed a long row of about 20 e-gates just in front of the non-EU booths. Looks like they will be using these in the near future?
