cue ball touching object ball

Rules 6.7 (double hit/frozen ball) of WPA states: if the cue ball is touching an object ball at start of the shot, it is legal to shoot towards or partly into the ball(provided it is legal target within the rules of the game) and if the ball is moved by such a shot, it is considered to have been contacted by the cue ball.(Even though it may be legal to shoot towards such a touching or "frozen" ball, care must be taken not to violate the rules in the first paragraph if there are additional balls close by.)

Question: does it mean that one can play a ball touching the cue ball if it is the only object ball and / or there are no other group ball in the proximity

When the CB is very close to but not touching the OB, one must take great care to avoid a double hit of the cue-tip and the CB.

This rule enables a shot that would not be possible otherwise. When the CB is touching the OB, high speed cameras can record that stroking the CB into the OB will result in a double hit if the cue stick is angled vertically. Thus raising the butt of the cue is not a legal shot when both balls are touching. Using a straight level stroke, the impact of the cue-tip to the CB is immediately felt by the OB since it is already touching, the CB may end up touching the cue-tip for a few more milliseconds, but it does not leave the tip and come back and make a second contact with the tip.

So there are 3 distances where different rules apply: A) long distance (normal rules), B) short distance (watch for double hits carefuly), and C) touching (double hit not possible when cue-stick is level).
