Confusing little bug(?)

[Kajsh 1]

So my brother has a group of friends that play DayZ, but he didn't have the game while I did. I decided to let him use my account to play cause I was busy that week. He ends up meeting with those guys and getting geared the fuck up like a boss.

My dilemma is this.

We have two gaming PCs, I dont know the specs, but they're perfect for Arma 2, but thats not the point. Thing is, we got Arma 2 CO on our second steam account so we can play together in DayZ. I knew my brother used my Steam for his DayZ profile, so I logged into His steam for my own DayZ. I launch DayZ on the second computer and I end up with his stuff, his location, and everything.

What I'm asking is this: Did I just spawn with his stuff in his location from a new save, or am I still using his account no matter what Arma 2 profile or STEAM profile I use? Is it the computer that he played on last? Because I want to start on a clean slate, but it would be cool if I suddenly had his Ghillie, M4, colt, ammo, bandages, alicepacks, vehicles, etc etc, but I dont want to squander it by not knowing if its his or not.

I would figure this out WITH him, but he's at work until 11PM easern time.

So if I dont get a reply by then, I might end up fixing it with him, just some input would be appreciated.
