is something of a misnomer. My understanding of this topic from reading the articles is that some companies where loading both Win2000 and WinXP on each computer and leaving the choice of which to use to the buyer. The first time they booted they would make the decision, and the other choice would be removed. Only one license would've existed in this case, covering the OS chosen.

That is not the same thing as a company putting two OSes on a computer (both being fully licensed versions) to be switched between as the user wishes. This is the scenario covered in the settlement.
