The knob being gone shouldn't drain the lowers, because that bolt and the hole through the bolt for the knob both goes into the damper shaft, no opening into the lowers.
I also don't see how it would drain the damper, though, because that would mean that the damper would leak whenever you took the lowers off. I don't think the damper shaft even has oil in it anyway, because how would it be held back by a hex key fitting into a hex hole? There is no o-ring on the part of the knob that goes into the damper.
I think the knob loss and the leaking were coincidental, the leak being just from a loose bottom bolt.
This goes with: "At the end of the day I noticed a loss in rebound damping". Why would it just be rebound damping affected by loss of damper oil, and not compression damping as well? I think that was just in your head after you noticed the oil.
