No, not quite. It's based on the series crossover used by Scanspeak and Peerless at times, with the low frequency sections merged.
It provides a gentle slope in the crossover region, but then goes to 12dB/oct. At the crossover freq, the drivers are in series, either side of the Fo the Xl or Xc shunt the driver, providing full drive to the other driver.
The Auto transformers are used as chokes, in the 10mH region, with low R.

edit: The lower transformer changes the Z seen by the amp/s to 2 ohms, which is shared between the two channels. I.E. 4 ohms load per channel.
No smoke, blown fuses or 3 way short circuits.
