What does fluid mean in this case?
Is that "smooth, relaxed, and graceful" as the second definition of Longman (below) shows?

fluid - Definition from Longman English Dictionary Online
1 a situation that is fluid is likely to change
2 fluid movements are smooth, relaxed, and graceful: a loose, fluid style of dancing
3 a fluid substance is a liquid

Thank you.

Yes, that is the idea.

"Smooth" is the main gist.
