Practice putting is allowed after the completion of a hole on the same green, a practice green or the tee box of the next hole to be played.
7-2. During Round
A player must not make a practice stroke during play of a hole. Between the play of two holes, a player must not make a practice stroke, except that he may practice putting or chipping on or near:
(a) the putting green of the hole last played,
(b) any practice putting green, or
© the teeing ground of the next hole to be played in the round,
provided a practice stroke is not made from a hazard and does not unduly delay play (Rule 6-7).
Strokes made in continuing the play of a hole, the result of which has been decided, are not practice strokes.
Absolutely correct. Keep in mind however, that note 2 to the Practice rule is often instituted as a condition of the competition, and is in fact in force for tour events. This local rule is NOT in force at USGA events like the US Open, but you seldom see players take advantage of it as they are so used to not being allowed to:
Note 2: The Committee may, in the conditions of a competition (Rule 33-1), prohibit:
(a) practice on or near the putting green of the hole last played, and
(b) rolling a ball on the putting green of the hole last played.
