PA5922L Taking The ECP Fast Lane

This slow vehicle PA5922L tried to cut into my lane in front but failed to and went behind me. Later he drove onto the fast lane (lane 1) of the expressway (ECP towards airport before Rochore Exit). Actually his lane was not obstructed nor slow, and I didn't undertand why he need to take the fast lane.
