Well, Piper conforms to the Perforce API-ish, and Android and Chrome are both on Git.

Mercurial was pushed internally as being the "better" (for some dimension of better) between it and Git back in 2010, but I think even the most hardline Mercurial fans have realized that in order to meet developers in the middle in 2015, we need to use Git for our open-source releases. We have a large investment in Gerrit [1] and Github [2] now.

So the Mercurial comment is probably entirely based on scaling and replacement for the Piper Perforce API, rather than anything externally facing.

Though both Android and Chromium still build in a way more similar to that for a monolithic repo. They use repo and depot_tools, respectively, as abstractions on top of Git in order to clone and manage all their Git repositories together as if they were a single large repository.
