I genuinely have no idea what it is meant to mean in the context it uses it. Load-bearing etc is annoying but roughly understandable, some of the opus5 classics are completely out there. I'm a native English speaker as well, I shudder to think what a second language speaker would do (even if they were very confident with the language!).
