The three points is only of concern for a dribbler.
FireDoc is correct. If the back court foot is raised the player now has the ball in his hands and his location is in the front court. If he now places his foot down again into the back court THIS IS A VIOLATION.
See Rules 4-4-4, 4-35-1, 2, & 3, See case play 4.4.1 (specifically)
