An older gentleman looks at the camera while he is building a deck.
An older gentleman looks away from the camera while he is building a birdhouse.
An older gentleman either looks at the camera while he is building a deck or looks away from the camera while he is building a birdhouse.
A deck is something that goes into water, and a birdhouse goes into a tree.
You cannot look at something and look away from it at the same time and could not be building a deck and a birdhouse at the same time.
