it's very common for meeting planners on this level to get the points or miles accrued for a big meeting like this. This is part of the resaon why indviduals don't get points on a stay when it is billed to a master account....because SOMEONE is often getting the points there.

I assume your company knows she is getting the points and has no problem with it, and in fact has made that one of the perks for the headaches she goes through. If your company is OK with it there's probably not much you can (or should) do.

If the company isn;t aware of the points value they are missing I suppose you could call it to their attention. But to me it's HER compensation and isn't necessarily your concern - unless you paid for your own room.
