From the article:
The deal gives Microsoft the exclusive right to match any offer for 30% or more of Nvidia's outstanding shares by a third-party." The agreement appears to be over 10 years old, dating back to the time of the contract for the GPU of the original X-Box.
This doesn't really do anything other than keep nVidia out of the hands of a competitor. It doesn't sound like this contract really helps if Microsoft wanted to buy nVidia without other buyers involved.
Basically, they recognized that they were very reliant on NVidia's technology, and while buying from NVidia is cheaper than making it themselves, they mitigated risk of losing that option by giving them the chance to pony up to keep any other company, competitor or not, from changing things.
The deal had to do with the original XBox. Nvidia was doing less well at that time catering to enthusiasts and thus if taken over, would pose a big danger to the XBox with all the graphics IP possibly lost to a competitor like Sony and MS having to basically start over again.
