A "logical Upgrade" is an upgrade from a base product to the next package deal of said product. So instead of buying (in a games case) each DLC and other said items in the upgrade package separately, there would be a direct flat cost going from product A to B.
Package deals aren't always about cost. Accessibility and Convenience are also factors. Access to each individual item and products that we would not otherwise have been exposed to is one. Combining all said products into a single package makes it easier & convenient for consumers.
In Divinity: Original Sin's case the Digital Collector's Edition is crazy given that is has a second copy of the base game. Given that fact I'd pay more than the $30 for it. I'd pay the $30 for the DCE upgrade even if it didn't have the second copy because hey, I like to support the devs.
