To answer your question, the two (or three) counters on the right hand side are for J and *G, however there usually is one big line in front of the single checked baggage screening machine. I am usually walking directly to the staff at the machine and inquired if there is a priority given to J class flyers, and they always let me through instantly (earning the

faces of the people waiting in line)
There clearly are two entries on the two sides of the screening machine. However, past the machine, the two lines sometimes seem to merge into a single one. Feeding into a single agent, who sits at a J/Gold position, with no one at the Economy positions.
Sometimes there remain two lines past the machine, in which case the agent calls from the J line in priority. But it's not always like that. Was not last time I went through.
