Well, they're doing some kind of "pre-signaling" in the coinbase at the
moment, because the segwit2x project is still in alpha-phase according to
the timeline. They're just showing commitment.
I'm sure they will begin signaling on version bit 4/BIP91 as well as
actually running a segwit2x node when the time comes.

Segwit2x/BIP91/BIP148 will orphan miners that do not run a Segwit2x (or
BIP148) node, because they wouldn't have the new consensus rule of
requiring all blocks to signal for segwit.
I don't believe there would be any long lasting chainsplit though (because
of the ~80% hashrate support on segwit2x), perhaps 2-3 blocks if we get
unlucky.
