As someone who has used thunderhooves teleport on DH, I can say for a fact that charge/charging strike works just as normal with teleport movement.

They're referring to how if you use something like Charging Strike Roundtrip with teleport movement, you won't get the bonus range after being within 3 tiles of someone because you didn't actually step over tiles normally, so the game thinks that since you "haven't moved" then you shouldn't get more range on Roundtrip.
  
Charging Strike Mad Chop is another one affected by this. Turnover & Thousand Stab aren't affected because they don't get any extra benefits from moving across a bunch of tiles.
 
Retreating Swipe is affected still, AFAIK.
    
This is more or less why teleport movement can be detrimental to a Soldier, and why Sonic Speed could conflict with it (unless it'd be adjusted.)
 
Long story short, anything that is affected by the amount of tiles you moved while using Charge (I.E Retreating Swipe, Mad Chop, Roundtrip) conflicts with teleport movement because when you teleport move, the game doesn't register the amount of tiles you've moved for that purpose.

EDIT: shinken is affected too

Ah that makes sense, considering turnover and thousand stab were the only charging strike effects I ever cared about getting lol. I don't imagine it'd be that hard to change teleport movement to count tiles for the purposes of the effect though, if that's what everyone is fine with.
