For LayoutIntent/@FinishedDimensions the specification is quite concrete:
Specifies the width (X), height (Y) and depth (Z) in points, respectively, of the finished product Component after all finishing operations, including folding, trimming, etc.
But for LayoutIntent/@Dimensions the specification just states:
Specifies the width (X) and height (Y) in points, respectively, of the media or product Component unfolded.
