More likely it failed because the missing terminal caused the coil voltage rise to go to maximum as no reachable path to ground. That spark may jump to the next available terminal as it nears. That gives that cylinder a grossly advanced spark. This can hammer out ring lands or head gasket. I think the rotor/button fail is simple wear item. They do that over time or if contact is bad. The rotor could have initially whacked the cap if not perfectly homed or poorly made. I have seen caps where the terminal(s) were not cut and the rotor would collide. On HEI that flat terminal if rotated can grab.
