Honestly, I don't think that's what it is. I really feel like it's more regional policy than anything else. Although my time was very short with the lens, I don't think anyone in the US had much more time with it. I think Fro had it a couple of days, but I also think his schedule is easier for Nikon to manage since he's very close to their NY HQ. For me, I was traveling and they had to work around my schedule and really went out of their way to squeeze me in. Time was short, but the rep flew in and out the same day (about a 4.5 hour flight each way )and that really had to be grueling for him but he never complained once and repeatedly said it wasn't a big deal. The truth is, it seems like Nikon USA has a very tight schedule and I think it's that more than anything else - and they have a very strict policy about not letting people use the lens without the rep there. My guess is that they were burned in the past.
