Shoulder mount has been around for a long time. You pose against the pole, then pull yourself up and into something on the pole in the air. Sometimes the position you end up in after lifting puts you in the perfect spot to do something else, sometimes like with the death lay shoulder mount is the only way to get into it.
I've shown 3 different hand positions for shoulder mount because not everyone is comfortable with the cup grip and the princess grip takes a lot of shoulder rotation that should not be done on an injured or otherwise unhealthy joint.
The third way with the funky hand grip should be the least taxing on the shoulders.
