\ncline[nodesepB=2.3mm]{->}{O}{B}
*XOR*
\ncline{-}{O}{B}

Well that is exactly what I did, there are no conventions as far as I am 
concerned, even using different colors for each arrow would lead to an 
undesired overlapping effect.

My strategy would be "least worse", I give seperation to one element, so 
the rest gets visual in the hope that the element not pointing directly 
to that vertex is assumed to do so. an alternative would be not to use 
an arrowhead for {O}{B}.
