Yeah, but you never make a netlist from them. So the "pins" and  
"nets" could just be lines and it would make no difference. Also  
IEC417/ground.sym in the current 1.4 release is poisonous to real  
schematics, although Stuart has fixed it in the dev version.

The IEC417 symbols are graphics without the formal topological  
meaning of schematic symbols. "Pins" generally (but not always!)  
represent ports, not nets. They are a path to madness for newbies who  
don't understand this.
