Not that I speak Portuguese, but it would be highly irregular to still be having a conversation that deep when the RAD ALT calls out 2,500' - never mind that much discussion into the flare.
I've always found that the guys and gals I fly with are pretty good about the Sterile Cockpit rule. We all recognize as a group that there is a difference between flying in severe clear conditions to sitting in solid IMC from take-off to minima, so we adjust accordingly. As Piltdown Man alluded to, total concentration can be very tiring to the point of becoming unsafe in certain conditions.
