As your wagon body rolls side to side, most noticably with big or rapid steering corrections, the rear axle is steering the car. As this is unexpected that immediately requires another steering correction. As so it goes.
A little known fact is that when Rack & Pinion steering was introduced to the utes with the XH models (XG still had a steering box, pitman arm etc) the front mounting eye of the rear springs was lowered to counter this effect. The quicker action of the R&P making the utes very nervous to drive, something that hadn't been so noticable with the slower acting steering box design.

That's an awesome fact. Was wondering why they lowered the front eye on XHs. The fact that XHs also ran a slower ratio steering rack (21:1) compared to EF/EF sedan(18.5:1) only proves this fact even more. XH XRs ran the sedan ratio however. FYI i replaced the XH rack with an EL one and the car drives so much better with the sedan steering rack!
