From the C# Language Spec (sec 8.9.5 The throw statement):
"When an exception is thrown, control is transferred to the first catch
clause in an enclosing try statement that can handle the exception. "

The operative word being "enclosing." Control shouldn't transfer to any
catch block in the same try, it should always propagate outwards.

There is a excruciatingly detailed process description of exeception
propagation in section 8.9.5 of the spec.  Perhaps that would help?
