Correct...when the car's circuitry sends the brake and turn signals (two separate signals) to the box, it senses the brake signal and activates both sides...then when the turn signal comes into the box, it senses the correct turn signal, and directs the on/off sequence to the proper side, over-riding the brake signal comand...and thereby allowing the turn signal to operate ALL THE WHILE blocking the correct turn signal information to ride the brake signal buss over to the other side and pulse the signal on the other side...lots of "logic-steering" diodes involved...
It's easier to throw the funky one out and buy new...
Or...
Just wire the trailer to match the lighting signals from the car towing it...
