Yes. It depends how you envisage it. It's also about timing - that change in direction before it becomes an actual step. I agree, it is a little like a basic volcada.
I tend to envisage it almost as leading a forward ocho to my left, but suspending that as the follower's left foot comes forward in front of their right foot, then leading back into a cross. Essentially movement of my torso to engender the follower's movement. So, sort of like a very slow, precise, controlled, mini, basic volcada.
Do you move the followers feet at all
Yes. It's the leader's which don't move. You can 'cheat' by taking a small side step as if you were about to lead a forward ocho, or even lead a more extensive part of that forward ocho. Or lead the follower to a small step back on their right foot.
I put it as a 'milestone' with the cross since, I guess, it embodies all the motion of the torso to lead that basic cross, but without actual steps.
The first milestone is where you actually lead the follower to an [unexpected**] cross - from a walk, say. This milestone is where you can deploy the bodily movement to just engender that cross from a stationary position.
** The follower isn't just doing a cross because they've learned some sequence where they expect a cross.
Lots of 'milestones' along the way which is any long list of step names. I wouldn't list caminata nor abrazo since those are always works in progress. (You think you've cracked it; but find you haven't)
None of them really matter as a dance achievement beyond actually leading the follower into an AT characteristic cross with musicality.
