I assumed the lurch he was talking about was the pulling into the  
swing. I'm not sure what the pedagogical (or Terpsichorean) advantage  
is in describing it as something willfully inelegant, but I do think  
that's what he's referring to.
When I teach beginners, I describe the point of the balance as moving  
you away from (while connected to) your partner so that you can pull  
in to your partner as you begin the swing (California twirl, etc.).  
With experienced dancers, it can be worth reminding them that fancy  
balances that end without that tension in the arms lose the pulling- 
in aspect.

 My experience is that most dancers do some sort of footwork - they  
 step
 forward with a 1-2-3 and back with a 1-2-3 or do a step and kick  
 across
 or anything else they fancy in the way of footwork.
 What is the general view?  What do you teach when you teach a balance
 before a swing? What do people actually do on the dance-floor?
