Pretty much, I'm not sure who Ted heard that from, would have been nice if he said someone at Mclaren told him that or it's just a rumour in the paddock. Because that rumour has been around as speculation for the past few weeks and frankly the way Ted/Sky are now it wouldn't surprise me if he just used that and took it as fact.
Aside from the fact that engine homologation needs to both be done by 28th Feb AND have the plans for that engine by 14th Feb which obviously has already happened, it as you say suggests the biggest problem for Honda remains... dyno testing.
They should at this stage have several engines running 24/7 and KNOW which set of parts IS better. That they don't is worrying and to me simply reinforces the idea that their testing in the lab simply isn't anywhere near good enough.
One engine maker brought an engine to Australia that wasn't used in testing last year, Renault... they changed it between testing and the first race with the piston update and wow did that not go well for them. Taking a rushed 'new' engine spec that you haven't tested screams disaster.
