That's literally the point of these videos. I explain what I'm doing and what I'm thinking the entire time. If there's a portion of the puzzle where I'm being too vague or ambiguous, I'm happy to explain something further.
There's no need to be rude about it. Also, I literally explain exactly what I'm doing while pointing at the squares for the 24x. "This can only be 6 and 4, while this can only be 7 and 4. That means the 4 can't go here (and I place the 6 and 4 in the 24)." If there's something that's confusing to you, I'm happy to help, but I think I explained that one pretty clearly.
I thought the explanation was clear enough. He had just put "47" in the two blocks for 28x, then said out loud "and then the 4 can't go here," pointing to the square from 24x that is in the same row with the 4&7 in 28x.
