So, tackled player sets the ball back. Teammate arrives and stops over the ball then picks up the ball and goes forward. Has a mono-ruck formed? Have off-side lines been established?
If the arriving player scoops up the ball and doesn't stop then we have a tackle but no ruck. But what if he momentarily stops? How quick is 'immediate'? Can he still pick up the ball until an opponent joins?
This seems like a very fuzzy area.
ChrisR and fellow learned friends. Please STOP dancing on pin heads and semantics.
The meaning of the WR is clear and is designed to prevent the practice that was displayed by the Italians during the 6N of 2017.
In essence, when ANY player presents over the ball after a tackle the off-side lines are established - as per a ruck. The tackler now has to come through the gate before challenging for the ball.
A true RUCK is formed as per the 'old' Laws when two players are in contact over the ball, and contest by hands must cease.
However, in relation to the last point, if the first arriving player is trying to secure the ball from the tackled player I would (respectfully) suggest that you pause and see if the player wins the ball. Last thing you want to do (at this stage of the phase of play) is call "RUCK!" and for the first player to stand up with the ball in his/her hands! Let it breath. Know when not to blow.
Yes, it is true that the phraseology used by WR could have been better, but one needs to understand the reasons and thinking behind they have made the change.
The same is true for the tackler having to go through the gate. How many times have we had 'debates' as to who was the tackler and who the tackler assist? Easy solution now. They both have to go through the gate

Simples IMHO
