That's all true. However, the commercial license included this:
"You must purchase a Qt Commercial Developer License from us or from one of our authorized resellers before you start developing commercial software. The Qt Commercial Developer License does not allow the incorporation of code developed with the Qt GNU LGPL v. 2.1 or GNU GPL v. 3.0 license versions into a commercial product."
Basically, you have to choose LGPL or commercial before you start your project. You can only transition from commercial to LGPL, not LGPL to commercial.
They do that to prevent specifically the thing you're suggesting, though they're probably aiming it more at large companies with many developers, so those guys don't just buy 1 license.
