Want to know what method is causing the update to a related table

I am trying to make sense of these two posts from these two very talented people.

Can I use call contextBPMdata.Character01 on BOL.UpdateLinks method directive and rely firmly on it being passed to the callcontextBPMData.Charcter01 value for the data directive on shiphead… I tried it out and I see that the value is passing, it’s actually working, which is super cool and maybe an answer to this whole thing… but I’d love to understand WHY it works or a little more about callContextBpmData… I know I have over the years but I never put it all together and tinkered with it to solidify a complete understanding.
