Just speculation, but the elephant in the room is that vehicle probably spent 10-20 days in transit, was turned down on delivery every few weeks due to age (old console, heated steering wheel) or quality. This is the first I've ever heard of Tesla offering to match pricing from months ago, so I assume they are also needing it to be delivered.
Rather than go to the back of the line again, it's more like you have gone back to where you were, but no longer have the "fast pass" advantage.
Anecdotal, but I ordered April 5th, latest dates were June 21-30, and have been 5-9 weeks since last week, so we're all on the same rollercoaster together!
