Is this just a roll cast preceeded by a perry poke?

http://www.newzealandfishing.com/new-zealand-fishing/tongariro-roll-cast.htm -- ignoring the snap-cast thing he does at the start -- perry poke + roll cast?

And a "perry poke" is just a means of walking/hopping the anchor closer to where you want to cast from right?  To load the rod for a good roll cast?  Wiggles.  

And the snake roll is just how you'd start a snap cast (taut line, rod kept low), but you go into a roll cast right before the snap, causing the anchor land by you?  (for right bank facing downstream -- downstream wind, cast right-handed all stuff happening on right side?).  Then a regular roll cast.  

Most of this stuff seems like they just named things you'd learn naturally by hitting yourself in the face and/or making unloaded, poor roll casts.  I gotta get a long rod so I look cool --
