inconsistent refinement behavior

The following behavior appears to be inconsistent:

In:	Assuming[x==0, Refine[Infinity/x]]
Out:	ComplexInfinity

In:	Assuming[x>0, Refine[Infinity/x]]
Out:	Infinity

In:	Assuming[x>=0, Refine[Infinity/x]]
Out:	Infinity

The third example should return unrefined given the first two examples. Is 
there an explanation?
