Aren't those the same thing?

In your example, sure, but they are seldom used that way. For example:
verb
  CheckThing()
    if(usr.thing == src.thing)
      // Ermm... don't want anything to happen here
    else
      usr << "BooHoo"

verb
  CheckThing()
    if(usr.thing != src.thing)
      usr << "BooHoo"

As you can see, the second example is much nicer. :)

I'd probably more prone to use the first one, rather than the second.

Unfortunantly until DM has cool compiler functionality that preprocesses expressions which can be computed at compile time you can't do anything like this with const variables.

That's certainly true, but most cases don't fall into that category.
