yes. but apparently he had a group of couriers, so we don't know if the couriers who were running the USB disks to internet café's were the same as the two brothers who owned the house
apparently he had a number of trusted couriers, and judging from what I have read on tracking these couriers down[1], it wouldn't surprise me if he had multiple levels of courier for his email
[1] apparently the couriers were so good at counter-surveillance that even when the CIA had tracked one of the brothers down to Pakistan, it took them two years to link them to the compound, since they both took exhaustive counter-intelligence measures to make sure they were not tracked. amazing story
