Yeah, I cringed at that part too. The trick with desoldering is that sometimes you need to add more solder before you can remove it. If a joint won't desolder, the easiest solution is to add a bit more solder until it balls up, then suck it all away with a spring-loaded solder pump. I find desoldering braid a bit tricker, but the secret there is to prime the braid with a bit of solder to improve heat transfer before holding it to the joint.
