Sorry that this wasn't clear. veOrientationEnabled is the global variable that (I'm assuming) will be set by the Optimizely experiment. For the Optimizely experiment I set up to test this, the code for Variation #1 is simply:

window.veOrientationEnabled = true;

...while the control did not have any code at all. That variable was meant to signify, not that the feature itself is disabled or enabled, but that the orientation dialog is enabled for that user ...if the other conditions allow for it to be displayed. I can change that variable name to something else if it's too confusing.
