Not quite. The text should be interpreted as saying that the individual 
resource specific filter is applied first.

Silvestr: ok thanks, it is now clear to me.

Why is F2 being propagated?

Hisham

Silvestr: I guess you mean the second propagation - you're right it is
my fault, F2 is not being propagated but anyway it is applied to bob
because it applies to all resources in list2. 

The result of is the same - bob is filtered by both F1 and F2. Is it
correct?
