Again, both still trigger. This would imply other before effects triggering on character death would also trigger. In which case GG would steal an upgrade regardless.
Lukas was pretty clear in his answer that only one copy triggers. I have no idea what the timing is which leads to only one triggering, but that's what he said.
Also worth noting that the clarification section you're referring to says nothing about triggering - it says that only one resolves.
