I think, while swinging the Graftek toward the post, the tubes would slide out of all the lug sockets and the bike would fall to pieces, without making any contact with the post. So, it would fail the test. Afterwards, I would fit the pieces together again and ride the bike away. So, it would pass the test. Given this fail-pass duality I would then rebadge/rename the bike the Graftek Quantum.
The only failures in Graftek frames that I'm aware of were in the the adhesive holding the tubes into the lugs so your predictions could happen.
The adhesive failures started happening while the frames were still being produced. It would be years before adequate adhesives would be developed. Take the glued together Raleighs of the 1990s foe examples.
The Graftek top and down tubes would probably bounce of of the pole while all of the other frame parts went flying!
...verktyg and iab would both win their respective argument.
What argument, I have no dog in this fight!
