So reading between the lines - the bracket holding the helium tank (inside the oxygen tank) broke, the helium tank ripped away from it's plumbing (pressure lines and valve(s)) and the high pressure gas contained in it escaped into the oxygen tank causing it to burst.

The SpaceX description is a little vague about the plumbing, I'd like to know more about that - is it an on off vale that opens and closes under command of the flight computer to maintain pressure, or is it a modulated valve that is controlled by a PID loop or the like.
