Am I propagating this peperomia pepperspot right?

I bought a pepperomia pepperspot today, and when I brought it home and uncoiled it (the vining bit was wrapped around nesting in the store), some of the vines snapped off. I decided to try propagating them in water, since I do that with pothos and spider plants. Never done it with peperomia before. Is this right? The last picture is the plant it came from, after I un-nested the vines and let them dangle.
