I had been refreshing my razor with the Dovo black paste on a fabric side of my strop quite successfully until it just wasn't feeling sharp enough to get a really good shave, so as I also could find anything conclusive about applying paste to the back of the leather side I gave it ago.

The result was not good, I could still shave but it seemed worse than before I used the red paste, the razor was very jumpy and rather than glide across my face it would jump across in a stuttering motion.

I think this might have something to do with the reverse of the leather side on my strop is not a smooth surface like to front or the fabric side, so in my opinion and after trying for myself I don't think it is suitable for using paste in my humble opinion.
Possibly your razor as beyond help with any pastes & simply needed honing.
