You're wrong. THIS IS NOT NOT NOT DLX!In answering another poster, this is DLX, and you CAN do it with every character. The thing is, it is not very useful for some characters, say Captain Falcon, who instead of sliding with usmash he stays in place when using DLX and scores no additional hit like Snake, Wario, or Falco. And for most characters, this is extremely hard except for the three previously mentioned characters. Try training in 1/4 mode if you don't believe me.
...this technique is done WITHOUT any prior hits being landed to the enemy. You do the move and slide across the board without hitting. Your own post aboves proves my point.
"he stays in one place when using DLX and scores no ADDITIONAL hit."
...there is no PRIMARY hit required for the dash cancelling Up-Smash technique, therefore its not the same.
