Yes, and it is perfectly correct to write it that way, or to write (7=12359)b7p13589. Either one is correct as a Boolean expression, correct in the puzzle, and establishes the single link. I only avoid the shortened form because some folks find it to be less clear.
OK, but whether the ALS node linking is single, double, triple, etc., I read your other comments as saying that the safest rule is to list only the actual linking digits, even if "less clear." I can live with that!
