While it was not originally true, the revised ruling on "constant" means that an environmental trigger can now simultaneously trigger multiple effects in one item. That doesn't mean other triggers necessarily can, but certainly some can.
"This seems to indicate that first, the triggering effect is resolved, and only then does it activate the Linked effect." - That's not really how it works. It can work that way. But it can also fire off the linked one first, as is necessary for MuVi. This shows up repeatedly in canon.
Separately, I really like silveroak's superposition version if used in a modern game.
