So now we know you have a good sense of humor , lets look at the time line .

Go to 5 secs and stop the video, your turn in entrance is early , reference the amount of road you have to your right . Then 6 secs you are already on the yellow line , this shows a set up for an early apex.
If you were to dive deeper into the turn, following the outside white line until the right tire touched it, or just before , and then made your turn in , the result would be no need for crossing the yellow line and a better exit at full throttle
There are times not to go out to the edge of the white line for reference. For example, if there is gravel or debris on the edge , or an obvious amount of camber change , this is info telling you not to go there . For the most part on two lane roads , following the outside white line into the turn and judging when to start your turn is very helpful. The geometry of the two lane road just works out that way
Just some thoughts

I could go on and on , bla bla
