To the extent that is true, it would reward owners whose teams did better in the previous round - which seems like a reasonable thing in my opinion.
However, without any sort of formal study, I think the draft order advantage all depends on the overall distribution of teams in each draft. In some leagues I think the advantage goes to those who draft late in round 1 and early in round 2. I know in this most recent draft there were a couple of leagues when I think having draft picks 12, 13, 36 was a significant advantage over having 1, 24, 25.
I'm obviously not the only one who thinks that way...in the very first round of this tournament there were several owners who specifically signed up for the last slot in certain leagues - presumably because they felt there was an advantage to doing so.
