Wrong message shown for app-pinning/unpinning

I'm using the Android feature to Pin the app using the the startLockTask() function. This shows a guide (screenshot attached) for how to unpin the app. The guide says, "touch and hold Back and Overview at the same time" however that is not how the screen can be unpinned. If you meddle around with the back key, it gives a toast , "To unpin this screen, press and hold the Search key". The real way to do it is to press and hold the Overview key (aka Recent Screen key) to unpin it (Also Zebra devices have a different icon for the Overview key than the standard Android devices. It is an ellipse rather than a square).

Can anything be done for this?
