IMHO, one thing to consider is why the PNF seems so surprised: "OLha isso!!" (look AT this!!) and calls: "Desacelera!!" (decelerate!!). It looks to me that his (PNF) priority was calling the PF's attention to what makes the aircraft accelerate, or the T/L.
1. Note that the PNF "abandoned" standard calls after the "Spoiller nada!!" (spoiller nothing!!) call.
2. PNF says: "Olha isso!!" (look at THIS) and then says: "Desacelera!!" (decelerate!!).
3. PF says: "Não dá, não dá!!" (can't do, can't do!!)
It seems to me that the crew was trying to deal with some abnormal situation related to the T/L (stuck, bent, loose?) all the time between touchdown and the time manual brakes were applied (11 seconds).
IMHO, if the problem was as simple as a "forgoten" T/L in CLB position, I believe the call after "Spoiller nada!!" (spoiller nothing!!) would be something like "Manete!!" (Throttle!!).
And PF's reply wouldn't be "Oops!!", followed by a movement bringing the T/L back to iddle?
Just a thought...
