It's fairly rigid, so it'll hold itself up into position, just as it is in that pic, until it's pulled down. I removed the A- and B-pillar trims, the visor, the sunroof ring and the top portion of the door seal. You can easily flex the headliner panel down enough to reach the ~8" in to get at the aspirator. That sunroof trim is a minor pain. Best I recall, you flex it enough that you think you're gonna break it. Bow the lateral (left-to-right) sides since they're longer and will flex more to bring the sides and corners in enough to pop it out and back in to position.
