Why is the "Did someone see it fall?" included?
Sounds like that question is irrelevant
It's just a mistake in the chart.
"No" should point somewhere else to continue classifying. Also "someone" is ambiguous -- it could mean "someone nearby" (not meteorite) or "someone far away" (possibly meteorite).

> If you saw a meteor and later found a stone, then the stone is not a meteorite
> Meteorite fragments land far from where you last saw the meteor and there is no way that observers at a single point on the Earth’s surface are going to find fragments of the meteorite. It requires triangulation from several viewpoints, usually with cameras.
But that's not what we're talking about here. https://news.ycombinator.com/item?id=39790272
If it's moving fast enough to be a glowing streak, it's going to land hundreds of miles away from you. If it's near enough that you found it, you have no chance of seeing it land (sort of like seeing a bullet whizzing past your head).
Keep in mind that this flowchart is to cut down the number of people who contact this person wondering if their rock is a meteorite, which it almost always is not. I first learned about this chart from this: https://xkcd.com/1723/
