Sorry, bud. I had no such intentions. Sincere apologies if you felt that way. Sometimes we see trolls on the internet, this site being no exception. I had no intentions of trifling your honest queries, nor of calling you a troll. Further, the ambiguous nature of your question confused me a little. In fact, to be very honest, I still don't see the problem with his answer, nor did the person who asked the question. He meant that a Rayquaza from gen 3 (R/S/E) or 4 (HG/SS), once transferred, could learn Dragon Ascent, because it was coded for it to be able to. The possibility of learning aries in gen 6, and not in the previous generations. This feature has made sure that previous versions of the game are not as obsolete as they can be, and that your previous efforts don't go in vain. Also, sentimental value from the old games is preserved.
I'm not sure why I typed all that, but here's a quick tl;dr: Sorry, wasn't looking to create drama.
