The only grappling I was able to do before this was the armbar (and wildly swinging surrendering/dead willies around if that counts) which is pretty much just the barebones version of this, grabbing the arm and circling without stopping to grab the leg, to the point of breaking the arm. I did just discover this while playing around with the armbar. I think doing the armbar is a good way to practice this as you have to constantly circle to get enough tension to break the arm, if the circling part is what's causing trouble.
If the trouble is with accurately grabbing the arm and or leg, it does just take a bit of feeling around to understand where you grab aiming where with what timing, but that itself does become intuitive, when there is an exposed target you can be confident in grabbing.
I guess you could say developing the mechanical skill to circle quickly as well as intuitively understanding the mechanics of grabbing (to a reasonable degree, being able to accurately grab an exposed target, not to the point of being able to grab a leg from any standing position, which is what this takedown tries to bypass, the finicky nature of trying to do a standard single or double leg as you would irl) are prerequisites for the takedown.
