Draco's intent, Dementors and Boggarts

There have been so many posts I can't even find the quotes i'm 
looking for. I'll try to summarize the ideas though I apologize for 
not quoting accurately.

The argument goes back and forth as to Draco's intent with his fake 
dementor prank. Most of people arguments depends on their view of 
how Draco thought the Dementors would effect Harry.

Someone said that the kids dressed in robes would not have the same 
effect as an actual Dementor because, well, it was fake. Im quite 
possibly missing a key piece of that idea but, again, I can't find 
it. Please respond again after I throw out my rebuttal.

Rebuttal: The Boggart Dementor was fake also yet it had the same 
effects as a real one on Harry as he attempted to learn the Patronus 
charm. So why would children dressed in robes effect the same way? 
Providing Harry believed them to be dementors.

Again, I feel like im missing something that i'm trying to say but I 
can't figure out what it is. :-\ 
I guess my whole point is what is the difference between a boggart 
dementor and a Draco dementor?

As for what Draco was thinking....
As I read the story the first time, I just imagined a teenager doing 
something he thought would be funny (to himself and his friends). I 
doubt he thought it through to killing Harry.
