There were two of them next to each other. Is that common at all?
How close is "next to"? Aircraft tend to have multiple lights, many symmetrically positioned. And when it's closer than you think and maneuvering, it may look as if the lights are moving non-linearly. Disappearance of a light can be explained too - the plane maneuvered in a way that its wing or fuselage blocked your view of the light.
