IANAL but the patent grant seems independent of the BSD License. React is BSD licensed. In addition, Facebook has provided a patent grant that applies under certain conditions.
The license for React says that Facebook has given me permission to use it. It doesn't seem that they can then sue me over patents related to the code, because they've just explicitly said I can use it.
If I sue Facebook over patents, then the patent grant no longer applies. But the BSD License does.
