Yes, you do have to jump. Just like when there is a fence in your way in the open world. I still wouldn't call fences a jumping puzzle. The path in Cliffhanger is wide and obvious and you don't have to use different length jumps and sprint like you do in Kugane Tower. There are only 3 jumps over a gap, I think. To me the challenge comes from dodging the bombs and I did not realize the few jumps are what other people find difficult.
