Sure, but we do know that the Realms-as-published is not the same as the Realms Greenwood had in his home game before publication. For example, the Great Glacier was bigger in the Greenwood-Realms, but they shrunk it to make room for Vaasa which was needed for the Bloodstone modules to fit into FR. I'm just not sure how much of the peripheral parts were Greenwood and how much were Grubb and others.
But that wasn't really my point. My main point was that at least the parts of FR to the north and west of the Sea of Stars are fairly coherent and fit together reasonably well. Golarion mostly does not. Each nation is essentially its own sub-setting with some things in common with the rest of the world, but mostly being its own thing. You likely wouldn't run a "Golarion" campaign, you'd run a Cheliax campaign, or a Varisia campaign, or a Numeria campaign (unless you do the Age of Ashes thing and teleport all over the place). That's similar to the way Mystara has the Adventuring Kingdom next door to the Byzantine Empire kingdom, which in turn borders the Viking Lands.
Many other settings are built to be more coherent. For example, Eberron has the core premise of the Kingdom of Galifar that covered (sort of) the whole of Khorvaire, but splintered in a civil war that just ended. This permeates the whole setting, and pretty much everything on Khorvaire fits into this vibe. If Eberron is a painting, Golarion is a picture formed from someone taking pieces from different jigsaw puzzles and fitting them together.
