Or possibly vice-versa: they appear to have been touting a desktop client app with remote rendering tech including a "codec" called orbx for a couple of years. So this could just be compiling the decoder via emscripten like Broadway and Route9 did for H.264 and VP8.
However, one of the Mozilla guys is quoted as saying it was built from the ground up for browsers (and the vague descriptions of the old codec, don't sound like a normal codec) so maybe they're just repurposing the name.
