Create Random Points tool does not respect min distance

So, I'm using the Create Random Points tool to create random points along roadways. These points should be 500 meters apart. I set the tool this way, yet I still wind up with points that are much closer than 500m from each other. All of my roads are merged into ONE row of the attribute table, as in all the lines are one feature, they are not separate lines with separate records, therefore, the tool should not be acting as if they are separate (thus allowing points to wind up within the minimum distance specified). Even if I trace the roadway with the measure tool (which shouldn't be how the tool works anyways as the distance is linear), there are many points that are well within the 500m from each other. I don't understand why the tool is doing this. Is there a way to fix it?


I was wondering if the tool calculates the minimum distance away from the last point it placed, rather than from all points it has placed, thus making it 500 meters from the last point it put down even though it could be right next to a point it put down two iterations ago? That would render the tool useless, so I doubt that's how it works, but that's all I can come up with to explain why this is happening.


Attached a picture to show how close it is placing points..
