Satan and his angels can see into the future but they are not allowed to see the entire future as it will play out. If they knew the future intimately, they would wreak more havok on the Earth than they do now.

This remote viewing session, I believe, was fueled by demonic forces. You may or may not agree, preferring to think of it as a gift given to certain human beings, powered by their minds alone.

This sort of information is classicly demonic - they could see what was coming, but not the extent of it.
