Can't help myself, but for something referred to as an "instinctive method", it never ceases to amaze me how much instruction on stance, grip, foot placement, bow angle etc..., etc..., etc... is apparently necessary in order to shoot a bow well that way.
Since the date traditional archery originated, which gets pushed back every few years, and now is estimated to be about 50,000 years ago, people have developed many effective ways of shooting the bow. Hunters, for maybe 30,000 years before the invention of agriculture, had very effective ways of shooting the bow, which are now lost to us. We know they were effective, because we are still here. The Mongol warriors under Gengis Khan had a very effective way of shooting the bow from horseback, which made them the scourge of Eastern Europe. Japanese medieval samurai had a very effective way of shooting the bow, which I don’t know much about. English and Welsh bowmen had a very effective way of shooting the bow, which made them victorious over much greater numbers of mounted knights. American Indians had a very effective way of shooting the bow, which enabled them to live off buffalo shot from horseback. In modern times, many of our forebears, such as Will and Maurice Thompson, Will Compton, Howard Hill, Fred Asbell, and Rick Welch never had a day of formal instruction in their lives, and did quite well for themselves. All of their styles of shooting the bow were different.
So if you would like to develop your own style, you’re in good company.
