ArcGIS Pro 3.0.1: What is referred by the “dangle tolerance” when working with the “find dangles” ready to use validation attribute rules?

For example, in the screenshot below, the “dangle tolerance” is set to be 20 meters. What does this geometrically represent? Many dangles are not identified!

All instances of dangle tolerance checks are best described here

Find Dangles—ArcGIS Pro | Documentation

The minimum distance to search for polyline nodes that are not connected to other features. Polyline features with nodes that are within this distance but not connected to other polyline features are returned as an error. The value must be greater than the input data source's x,y tolerance.

The default is the data source's x,y tolerance. The default unit of measure is the input data source's horizontal spatial reference.

Note:
When the spatial reference of the feature class is geographic (GCS), the tolerance is converted from degrees to meters.

Right. This rule is identified if any feature lies within the tolerance from the node of any other feature
