The voltage at the terminal oscillates leading the ring voltage by 
~90 degrees. See the ideal ring and terminal voltage waveforms for a 
lossless system in mode 20-21, for 1 V of input voltage:

At the end of the energy transfer, at 36 us, the output voltage is 
negative, but in almost identical modes 19-20 or 21-22 it would be 
positive. Mode 21-22 would result in:

Breakout probably occurs before the end of the energy transfer, anyway.

Yes. A capacitive transformer works in both directions, as a regular
transformer, when properly tuned.
