Google already knows about them. And has bet the future on WebM anyway. I trust Google's legal counsel more than I trust you. What if H.264 infringes on some of Google's patents? Google could countersue and go after members of MPEG-LA, or even end-users of H.264. Google's patent license only covers Google's WebM implementation.
You do realize that Google's legal counsel has very little say in this. Google's engineers are making the call and the counsel is just providing legal advice. The legal counsel doesn't know what is infringing on what. With that said, you'd probably say that you trust Google's engineers more than me. I'd hope so. You have no idea who I am.

Do you think the engineers wrote the patent license too?
