Borutos flying thunder god technique is inferior to Minatos in a number of ways, stated as such by the author, and even without the authors explanation its pretty clear cut what boruto cant do from simply reading the manga which whoever wrote this article clearly didn't. Minato didn't create the technique anyway, that's not to discredit him mind you, as he did take it to heights so great and with such mastery he had its inventor second hokage tobirama senju cycling from being impressed to curious and then shocked during the fourth shinobi war. Also tobirama himself stated that unlike the fourth hokage he couldn't use flying thunder god to teleport the entire shinobi alliance.
