I would disagree this is better security, security measures should be designed to prevent attackers not annoy the users. If they become to obnoxious which a 2 minute lockout certainly is it just encourages users to find ways to circumvent them themselves.
It's better security in an insecure environment. I have this on my laptop, though I try to always lock it if I move away.
At home, kids, partners, etc. should not see Redgate info. Not that they'd disclose it, but it is potentially something that a company is concerned about.
At one place, we weren't high security, but we were privileged users, so it was a big deal to lock our machines. Other admins had a game of messing with your background, colors, etc. if you didn't to try and remind you to lock your desktop
