Which is in essence, exactly what I said. Prior to Kit Kat, Touchless Controls did not override the launcher, after Kit Kat, it does, whether by design or a bug. (Look at the mic in the Google Search bar, it is hollow after Kit Kat --- It wasn't before Kit Kat). Again, there are threads about this exact issue on the Moto X forums, the XDA forums and Google+. Matt Jones (who works at Motorola) was looking into the issue.
The main issue is Touchless Controls are slower and you have to say "OK Google Now" each time to do contextual searches.
