What is "protein redox conformation"?

From an article by Frye et al. [1]:

Reduced glutathione (GSH) is the major intracellular redox buffer and is essential in free radical scavenging, redox homeostasis, maintenance of protein redox conformation and regulation of redox sensitive enzyme activity.

What is "maintenance of protein redox conformation"? Is it just fancy phrasing for "keeping proteins properly reduced, but not too much reduced, and properly oxidized, but not too much oxidized?
