[Lazarus] Canvas.PolyBezier docs is poor

[Alexey Tor.]

"Filled" help is poor: If the Filled Flag is set to TRUE then the 
resulting Poly-Bezier will be drawn as a Polygon.

??? does it mean that start and end points of a curve will be connected? 
does it mean that all parts of curve (with Continuous=false) will be 
connected? does it mean that all points (start-end and parts) will be 
connected and Brush filling is used?
