Yes, if you read that it says the default container format is called "libcontainer".  It "also supports" LXC.  Originally it was LXC only.  Then they switched to libcontainer... but they say they support several formats (including OpenVZ although I haven't seen any elaboration as to how) and plan to add more in the future.

Docs that were written before the move to libcontainer (and in all honesty, I'm not really sure what libcontainer is vs. LXC) won't mention it.  Everything after the move, should mention it.

For more information about libcontainer... and it was the 0.9 release of Docker that announced it (not 0.6 nor 1.0 as I had previously guessed)... can be found here:
