No it's not. This is a proper Faux Bar design, stinky is linkage driven single pivot. Stinky's have the dropout on the chain stay. Ellsowrth have theirs on the Seatstay, it makes a much better pivot point and a more constant chain length through the travel.
shred-nz-media is right, but i believe this is a true FOUR bar design, and stinkys are called faux (false) bar because they pretend to be 4-bar, but just kinda stink.
