It depends on what you want to believe. Lots of authors put little things in without concern for the possibility that it breaks established canon lore, just because those things are so little they can be ignored.
There have been many cases where "in a nanosecond", or "faster than a missile" or "faster than the eye could see" or something or the other has been used to describe an action. Does that mean the Force literally allows people to have FTL reflexes? Well, maybe. But it probably wasn't the author's intention.
Although! What if it was faster than light? Would that make too much of a difference to star wars lore? It's been-well established that it's almost impossible for anyone who's NOT a force wielder to be able to hurt a force wielder. So if the most powerful force wielders ever have FTL reaction speeds, does that really break the lore? I don't think so.
