I believe they're the same. I don't know for certain if 9 and 10 are the same but I'm using an old 9spd shifter on a 10spd chainset on one bike and the other way around on another bike. Did they all come in a groupset package? If so you could always ask the shop you got it from if it was correct.
I assumed it was the r/h shifter.
