Ya absolutely. Obviously that's not the purpose of the drill, but self defense is not so much about techniques, it's about managing adrenaline and having the mindset to kill or survive rather than freeze because it's so alien to you.
MT is a great in between step. If you slap some random person in the mall they will likely freeze up and turn their back to you, and MT gets you out of that habit. But it doesn't get you into the habit of thinking about killing someone and realizing what happens if you fail. Most martial artists are utterly delusional when it comes to thinking about this stuff because it's very unlikely someone is going to follow you into the locked foyer of your apartment as you fumble for the mail key and hit you in the back of the head with a pipe. The people training MA are most likely in their twenties and their idea of self defense is some drunk guy hitting on their girlfriend.
I've had all sorts of weapons pulled on me, and 1 used against me, and MA training was not particularly relevant. I wasn't thinking about those knife defense I learned when I saw a 9 inch serrated blade.
I know the military has done some really extensive studies of this stuff (
On Killing: The Psychological Cost of Learning to Kill in War and Society has some interesting stuff), and came to the same conclusion. H2H training doesn't need to be that in-depth, better to make the recruits miserable and stressed and force adrenaline dumps and physically fit and so on.
