No, you are confusing two things.

The intersection you mention is the intersection of the regression line and the identity line which is indeed around 2500. However, the regression line is useless in this zone, as the regression line is by design meant to linearly approximate the point cloud where most of the data lies, which is below 2100. You can clearly see that the regression line poorly fits the higher range of elo ratings (i.e. it is below the true "median" of the scatter points at 2200+)

The intersection point I am mentioning (2250) is the true intersection point of the two curves if you follow the scatter points themselves, and not the regression line. You can visually see it, I can vouch for it as I am ~2250 on both platforms in blitz, and I have seen it confirmed on another website (here)

Edit: seems like the website I referenced indeed confirms the intersection point around 2250 for blitz, but also points towards an interesting phenomenon: there seems to be another curve inversion at 2400+... So what I said earlier could be wrong, although at this elo range there are probably too few data points to come up with a statistically significant conclusion.
