Hello! The walkthrough you've watched was on an old build of the game and used an unintended solution at this point - so you'll have to figure out a different way. I will at least say it's definitely possible to grab that log above if you turn around, but once you've grabbed it you'll have to do something different with it. In the walkthrough, you'll notice they also don't use the 4-long log at the top, but that's now a necessary part of the solution!
