Three more points I like about GVT is that, by performing only two exercises per session, each movement remains a bit "fresher" with more space in the rotation since you're now using some of them every 2-3 weeks as opposed to weekly, for instance.
Secondly, the progressive nature of the sets renders the first 2-3 to serve as your "warm-up." 4-6 may be considered your "acclimation sets," while the remaining sets are your heavier "work" sets; for those who favor that method of training. Here, you're using the same station, same weight, etc. It's all built in!
Thirdly - and this is purely personal preference - I like volume and the ability to effectively overload the muscles with a lighter weight. GVT accomplishes both. My body responds better to volume, and lighter weight yields less stress on joints, tendons, etc. While it is certainly still possible to get injured and/or develop inflammation issues on GVT, I honestly believe it is less likely.
