1. Only true if there's copious amounts of oil to absorb the seasoning. Otherwise it might get absorbed by the rendered fat of the burger. Sometimes 50% or more of it gets lost, sometimes less.
2. It is better to underseason than overseason. If you overseason, you end up with an inedible salt mess. If you underseason, all it takes is a quick sprinkle before you eat it.
That being said, I think the picture in #6 looks perfectly fine. I'd use a dash more of pepper though.
I honestly don't understand seasoning a burger with pepper before grilling. By the time you're done, most of the flavor has been obliterated by the heat.
