fietsbob's got it. The word from my mechanic and the guy he hung with was "inside pulling". (The spokes coming out of the inner side of the flange at the top of the hub point back. These are the spokes that are loaded when you pedal or brake.) You did this so that when the chain lands between the last cog and the spokes, the spokes will do their best to kick the chain out. If you go outside pulling, that spokes will do their best to suck the chain in causing considerably more damage.

I always make a note of the damage from a jammed chain and whether the spokes were inside or outside pulling. There is considerable overlap between the two, but the pattern of worse damage from inside pulling is impressively consistent. (I've been taking notes for 40 years.)

Oh, that guy who used to hang with my mechanic? Sheldon Brown. (This I find actually funny. That rule was solidly planted in my brain for 25 years before I had any idea he became famous.)

Edited for clarity and typos.
