LuckyJ is correct. Most likely the PO exspearenced some amount of death wobble (straight axle shimmy) and figured if one stearing stabilizer is good then two is obviously better. It is true that a single pass stearing stabilizer shock, much like a single pass hydraulic ram is faster in one direction than the other and there was a definite perception at one time (1980s) that you could equal this out by utilizing a second stearing stabilizer shock placed in the the opposite direction (longitudinally) ... Today, with the advent of double pass adjustable stearing stabilizers there is no longer a need for the glamor harkening back to the 1980s representation of modern tech. Fortunately it's a good looking jeep and I don't see a freshly installed set of fluorescent pink triple blade windshield wipers.
All joking aside, dual stearing stabilizer shocks are a bit much, not adjustable and depending on the valving possably a bit overkill, with a tendency to mask a greater issue. It is entirely possible they were not placed there to hide/ deal with death wobble, in fact, they could just be there because the PO liked them. You may consider removing them and checking for the dreaded "death wobble" and then seek to repair its cause. If no "death wobble" exists, put them back on and drive that baby to your hearts content.
