Yup. Poor translation. Seems to refer to the same system that was used on the early Browning Superposed. Double triggers could function the way normal DT's do. But both barrels could also be fired with each of the individual triggers (one at a time). Front trigger would fire bottom barrel, then top. Rear trigger: reverse.
I'm still a little confused over the "divergent" thing--unless it maybe refers to one barrel set up for greater dispersion of the shot (with rifling). Relatively common on European woodcock guns.
