Grrr... Spektrum DX2.0 won't talk to Flux ESC

Damn, now it just gets weirder! I went ahead and tried rebinding the thing with throttle and steering in neutral and followed Spektrums steps and then all of a sudden, the ESC chimmed and it was ready and it worked normal with throttle and brake? Uhhh.....how is that possible? I haven't even programmed the ESC with the throttle endpoints! So, I power down the ESC and power it up with my throttle down and once again, it will not take the reverse/brake input even though it sees and reacts to my throttle input. What is going on here????
