Did the Land Raider Achilles foreshadow the new Hull Points system?

This has been bothering me ever since 6th edition came out. No, actually.. even before that - when the first "concrete" rumors and leaks flooded the blogosphere.

Before I added the side sponsons.. which were a PAIN to build.

So.. was the Land Raider Achilles an early sign for the Hull Points system - perhaps one of the biggest changes brought to us by 6th Edition? I think so.
But let me clarify the actual fact of the matter here:

Here are the early "Experimental Rules" of the Land Raider Achilles, as posted on the Forge World website as soon as the Land Raider Achilles was announced. Notice, for example, the original point cost of 300 points (compared to the actual, current point cost of 325 points.)

"... reduces the effects of all rolls on the damage chart made against it, by -1"

Before: Back then everyone was super excited, because it meant that a regular, non AP1 Glancing Hit couldn't even immobilize a Land Raider Achilles without actually destroying all of its weapons first, since a roll on the damage chart would have been at -3. Penetrating hits were only at -1, which meant that an actual, natural roll of a 6+ was needed to Wreck it. Add to that the immunity to the Lance and Melta special rules and the Land Raider Achilles became pretty resilient. This rustled the jimmies of a bunch of people who immediately yelled "OP! OP!", especially when it was announced that the Land Raider Achilles had the "Warhammer 40,000" stamp on it.

"reduces the effects of all rolls on the Damage chart caused by Penetrating hits by -1."

After: Shortly after the Experimental Rules were posted, there was an update (I think). I mean, I got the book pretty soon, so I also noticed it there. At first, the most obvious difference was the slightly gouged price of 325 points, but after a careful examination on my part I saw the changed wording of the Ferromantic Invulnerability special rule. It struck me as odd. Why would this amazing, super-special hull armor only work when it has been actually penetrated. Why didn't it affect Glancing hits or just ALL rolls on the Damage chart? Back then I saw it as a weird way to nerf the Land Raider Achilles by at least giving some armies the chance to deal with it somehow by Glancing it a bunch of times.

Using 6th Edition, though, it all makes sense. Glancing Hits no longer roll on the damage chart, they simply destroy one Hull Point from the vehicle. It is only Penetrating Hits that get to roll on the chart.
So it is possible that those responsible for the editing/rules of Imperial Armour Apocalype: Second Edition got a whiff of the new vehicle rules... pretty much a year before the actual release? We are constantly being told that Games Workshop and its sister company, Forge World, are pretty independent and separate and that the guys from FW have no idea about what's going on over at GW. It may be true.. but I still think it's weird and quite hard to believe, so I wouldn't be surprised if the book was written, or at least edited with 6th Edition in mind. Even if it was a year ago, I bet that coming up with a new Vehicle damage chart and the Hull Point system was one of the first things that was added to the book. It is just such an important, fundamental part of the game - there's no way that it was not a priority.

But then again knowing GW I wouldn't be surprised...

So whaddaya guys think? A possibility... or a coincidence?
