I have finally uploaded the updated version to OHM, not requiring the latest redistributables anymore (please verify that it works as intended).
I have also done the same treatment to my other MFD addons (

Sorry for the late reply.
You haven't missed anything; it is vessel-independent. The challenge with monitoring the load for a specific vessel, is that the MFD doesn't know which vessels are relevant for load logging.
As an example, it can't tell the difference between the AMSO LM and the rock vessels AMSO spawns when landing. One could then say that the MFD should log every in-sim vessel, but then take a complex simulation like ISS AtoZ, which has hundreds of components. That would not be a good strategy.
This is the reason for it being a bit dumb, and only recording the load on the current focus vessel.
