It doesn't work.
I installed game on 2nd phone and when there was a premium choice I used it. And on 1st phone when I resrarted episode I had to pay for this choice. So mod doesn't do anything, because in original game when you already paid diamonds for smth, you don't need to pay again when you restart this episode.
In your videos you are showing 1st episode of story and there are no premium choices, so in both videos mod is working.
