when faced with 2 top openers above a large pane...simply WFP one of the openers then bring your brush down, under and across AVOIDING the gap before moving brush up to clean second top opener.If you get any water in the gap between top openers, you will get a fan of water marks onto the main pane.That's a excellent piece of advice Steve k.Jeff.
