offset command, closed polyline

Summary

I've a problem with offset command. 
 You can see a similar problem in VectorCAD. 
 I draw a polyline composed by two arcs with these parameters: 
 An Arc with start point in -110, 0; end point 110, 0 and radius 110. 
 An Arc with start point in 110, 0; end point -110, 0 and radius 110, then CLose polyline. 
 I try the offset command with a value of 20 (point is inside the "circle"), but I can see only a point in -90, 0 instead of a circle inside the figure. 
 This are the command lines: 
 
 
 PolyLine start point: 
 -110,0  
 Next Point or [Arc/CLose/Undo]: 
 a  
 Specify Second point of arc or[Center,Radius,Line,CLose,Tangetial,Undo]: 
 r  
 Specify radius of arc: 
 110  
 Specify End point of arc: 
 110,0 
 Specify Second point of arc or[Center,Radius,Line,CLose,Tangetial,Undo]: 
 r  
 Specify radius of arc: 
 110  
 Specify End point of arc: 
 -110,0 
 Specify Second point of arc or[Center,Radius,Line,CLose,Tangetial,Undo]: 
 cl  
 Select Entity to Offset:  
 Offset Distance <0.100000>: 
 20  
 Side to offset:
