The confusion is nothing to do with spurious extra steps.

Quickstep correctly described a chasse roll to the RIGHT but the original question was about a chasse roll to the LEFT.

The two figures start with the opposite feet, move and turn in the opposite direction, and typically start and end in different alignments.

For chasse roll the left/right gives a clue, that is why I suggested referring to natural/reverse tumble turns to make the direction of turn clear.

Oops - you are right!

It wasn't a spurious extra step, it was a spurious other figure!

I haven't yet found a Rolling Chasse to the left. Most people I know do as Marcus Hilton demonstrated. After a Running Weave which is
1 and 2. 3. Followed by Double Side Locks. which is 1 2 and 3 and. Left foot now free for Reverse Movement
In the demonstration instructions this is followed by a Reverse Fallaway.
If Dave could say what is to follow it might throw some light onto whether the correct name is being used or not.

"I haven't yet found a Rolling Chasse to the left."

Well it's pretty common. As has been pointed out several times here, what we are talking about is essentially a chasse replacement for a tumble turn.

This is After a Running Weave which finishes with the right foot free to move. I would be interested to know wHat alignment a Rolling Chasse to the left finishes, ( the Tumble Turn also ) and to be followed by what.

"This is After a Running Weave which finishes with the right foot free to move. I would be interested to know wHat alignment a Rolling Chasse to the left finishes, ( the Tumble Turn also ) and to be followed by what."

Like many four-step figures, it ends in much the same sitaution as it begins. Man's right foot free. It could make a complete turn, preserving a DC direction of movement, or could turn only 3/8, either will work.

Any backwards reverse figure could follow, especially various lines - for example, a throwaway might be a common choice.

Then now is your chance to introduce the more advanced combination.

Taken from Geoffrey Hearn's book describing the Running Weave:

"Suggested Popular Combination:
Open Impetus - Running Weave - Side Cross.

Suggested Advanced Combination:
Hover Cross to PP - Running Weave - Chasse Roll to Left."

As I said in a much earlier post, his suggested follow to the chasse roll is a left hinge (commenced man RF back down LOD)

Found it. Chasse Roll to the left. starting with an Overturned Spin Turn. Turning Lock to finish open diagnal to the centre. Running Weave. Chasse Roll to a Left Whisk. Swivell to PP. Curved Feather. Finish facing against LOD.
I don't know but is a Rolling Chasse a Chasse Roll. The original thread was asking about a Rolling Chasse. The above is a Chasse Roll.

You treatment of this subject is rather interesting: apparently you don't accept anything is valid until you find it on one of your videos or written routines?

And then, even if there's a slight difference in naming, you still question it.

Everyone else accepted what the figure was days ago...

Do you think that an organization that is so exact, that sends material all over the world would call something by two different names in the same publication unless there was some difference. You tell me. I'm just asking.
