The Catalyst did explain to you that Shepard is the first to stand there, at that chamber, to converse with it, which caused it to rethink the cycle. So, nice try.
He didn't explain why Shepard standing in his chamber such a big deal though. How this connected to the whole synthetic-organics conflict he claims to prevent? 
Big deal or not, the point is that, he wasn't programmed that way, to give Shepard three choices. He wasn't holding anyone under gunpoint.
He could've let Shepard die, and then he would win. And he could've just changed his mind, and he would still win.
But he didn't. He presented your Shepard with three choices that did EXACTLY what he promised it would do, but you still refused. Ergo, your cycle dies. You lose. The other cycle might still win, but YOU lose.
