I think the precise opposite is the case. Most of the convergence (of graph lines) is at the start of a sample.
Over a small sample, it's easy to be + or - 2 buyins, so the lines will often cross a few times. Once you're 20 or 30 buyins above or below EV, it's unlikely that you'll have a "streak" of rungood/runbad that switches everything around. As has been said in the thread, your future expectation is to be EV neutral, so if you're +30 BI after 100k hands, your expectation is to be +30 BI after 200k or 1 million. It doesn't "even out" in the long run. Long-term results are on a "random walk". Half the time (?), the divergence (in absolute number of buyins) will get greater over time.
As shown by this variance simulation, the luckiest and unluckiest graph lines are getting further and further away from the mean:
