I think they do agree with you, but I also think they are trying to say one thing in addition. At what point does the pathway between A and B need to be in place in order for the particle to get from A to B. They seem to be saying that the pathway can be put into place remarkably late. In fact, the pathway can be put into place so late, if the particle were behaving according to Newtonian physics, the pathway would have been too late for the particle to follow it. But because the particle obeys quantum physics, it can still follow the pathway.
