Sharing Anchor With Climber

So since I've been taking pictures I've always set up my rope on nearby anchors by either climbing up myself or rapping down and setting up. I've been using the knot block method Petzl describes in this article without any issues : https://www.petzl.com/INT/en/Operators/Multi-pitch-rappelling-with-a-single-rope?ProductName=GRIGRI#Partie%202

Only difference is I've been doing them on sport rope anchors feeding my rope thru both sets of chains.

Question is would it be kosher to setup on the same line as the climber basically shooting from above? The anchors can hold the weight of 2 people right? Any setup issues y'all might foresee?

Sorry if it's a dumb question i just don't have a mentor and rely on self discovery and research.

anchors should definitely be strong enough for multiple people.

Your rigging might get in the way of the climber towards the end of the route though.

Yeah I guess no way around that. Was thinking more for when they are projecting.
