iOS7 Assistive Touch BUG?!

On iOS 7, if you have turn assistive touch on, and accessibility shortcut if set to assistive touch, you might be found a problem - cant show control center and notification center when you use accessibility shortcut (press home button 3 time to turn off assistive touch), even you at lock screen (take photo still works).😮

Press home button 3 time again to get assistive touch back on, and control center and notification center back to work!😀

Have no idea why accessibility shortcut can cause this problem, assistive touch is great way to extend our home button's life~
