The Clean Report[1] is not really clear on that but to my knowledge nested 
guards do not have fall-through semantics.

The report does mention this:

"To ensure that at least one of the alternatives of a nested guard will be 
successful, a nested guarded alternative must always have a 'default case' as 
last alternative."
