EW is describing a sort of sunset I haven't seen, so I can't with honesty say 'you know that time when...' - because you and I just don't share this experience with EW. But I can say this: just before sunset, shadows are long; everything has a shadow and is in shadow. At that moment, while close objects are unclear, distant ones - features in the landscape - are more clear. Perhaps this particular New England sunset has something to do with that.
