71 Duster 340, 727 Manual Valve Body - question...

Thinking you my be in 2 gears at the same time.
Is this a reverse shift pattern?
D, 2, 1...…..or 1, 2, D...….???
It kinda feels like that. It's a std shift pattern not reverse. It feels like it's in drive with the emergency brake on, but free wheels more than it would if that was the case. Thanks
