How Is "Super Laminate" flooring installed?
It seems to depend on the range of flooring that you choose.  I found a video on YouTube showing it without the tongues, and I also found a seller with some photographs showing the tongues on the edges of a piece.  

This review backs up that assessment:


  Loose Lay Vinyl Plank Flooring (you literally can just unbox the floor and then install without glue or
  anything!)
  
  Mid Level Vinyl Plank Flooring (this clicks together like laminate flooring and is INCREDIBLY well milled)
  
  High End Vinyl Plank Flooring (This is a wide planked handscraped floor that looks like wood and has a depth of  visual detail that can not be beat)
