Have a look at the documentation page for EdgeLabels and you'll find in 
the "More Information"-paragraph:

The following option settings can be used:
       	None	use no edge labels
       	"EdgeWeight"	use the edge weight as a label
       	{Subscript[v, i]\[UndirectedEdge]Subscript[v, 
j]->Subscript[lbl, ij],\[Ellipsis]}	label edge Subscript[v, 
i]\[UndirectedEdge]Subscript[v, j] with Subscript[lbl, ij] etc.

I think that is
  1. unmistakable
  2. not true
