Chances are, the two lobes of Ultima Thule orbit around a barycenter between them, in a plane at or near right angles to the New Horizons probe. That would make them return about the same amount of reflected light, at any time.If that's not the case, wedohave mystery to solve.
This scenario seems plausible to my layman's brain.
So what you're saying is that the amount of reflected light from the object would not change that much if the same amount of reflected surface is always pointed toward the light detecting instrument as the object rotates -- even if that rotation was of a dumbbell-shaped object.

Improbability. Not impossibility.
I luvs me a mystery!!!
This one should be readily solved in a week or so...
Then, there won't be much to do but wait and hope that things go according to plan. Around 10:00 a.m. EST on Jan. 1, the team expects to get a health and safety report from New Horizons letting them know it survived the encounter. The first up-close images of Ultima Thule are expected to arrive on Earth between 6:00 and 8:00 p.m. EST Jan. 1 (22:00 on Jan. 1 and 00:00 on Jan. 2 UTC), a NASA spokesperson said.
"From Ultima's orbit, we know that it is the most primordial object ever explored. I'm excited to see the surface features of this small world, particularly the craters on the surface," says Deputy Project Scientist Cathy Olkin of the Southwest Research Institute. "Young craters could provide a window to see the composition of the subsurface of Ultima. Also by counting the number and impactors that have hit Ultima, we can learn about the number of small objects in the outer solar system."
