So they get confused, right?
POSTED BY: Gianluca Gorni

Take a look at the InputForm. It will be pretty obvious. You need to "tag" the edges so edges with identical vertices aren't confused.

Graph[{Style[1  \!\(\*OverscriptBox[\(\[DirectedEdge]\), \(1\)]\) 1, Blue], 
1 \!\(\*OverscriptBox[\(\[DirectedEdge]\), \(2\)]\) 1, 
Style[1 \!\(\*OverscriptBox[\(\[DirectedEdge]\), \(3\)]\) 1, Red], 
Style[1 \!\(\*OverscriptBox[\(\[DirectedEdge]\), \(4\)]\) 1, Red, Dashed]}]

With no previous experience of Graph, I tried to reproduce your diagrams using Graph, and soon met puzzling behaviour:

Graph[{Style[1 -> 1, Blue],
  1 -> 1,
  Style[1 -> 1, Red],
  Style[1 -> 1, Red, Dashed]}]

Why do all edges come out blue? Why is the Dashed ignored?
