When the sunfoof on my 2011 Explorer is totally open and you hit the 'Slide' button the glass will close and then the cover. Same if you hit the open switch. First the cover will slide back and then the glass. The weird thing is if the roof is tilted, you have to hit the tilt button, wait, and then the open button. If the roof is tilted and I want it back I should just have to hit the 1 switch to perform both operations. Less distracting for the driver.
