 Well, I'll not say that the block was propagated.

 The block was accessible for the current call and the next call,
 i.e. with this example :
   
   def a
      yield "aa"
      b
   end
   
   def b
      yield "bb"
      c
   end
   
   def c
      yield "cc"
   end
   
   a {|l| p l}

 #a and #b can access the block, but #c give an error.

 Well, what you have written is interpreted

   @parent.parents(*args) & block()
