IMO ask to speak privately with your coach and have a theoretical discussion about it. Bear in mind that at 6 months there is alot you haven't been exposed to both in terms of theory and practice. I don't see your instructor getting pissed because you have a question.
On a side note since you asked for opinions, at 6 months, don't get too sidetracked from the basics with advanced techniques. You will end up screwing yourself with glaring holes in your game later on. By all means read and research the stuff, just don't focus on it to where you neglect the basics.
