I may have been referring to an earlier version of the diagram, when arrows
used to be bidirectional, and which made be believe the following exchange was
possible, as part of a larger request:
  HandlerD(intermediary)  --Block4--> HandlerG(receiver)
  HandlerD(intermediary)  <--Block4'-- HandlerG(receiver)

Tagging looks like an interesting candidate solution for implementing this
kind of exchange; but I guess, strictly speaking, you are right: there is no
implication in the diagram (or if there is one, it's probably the other way
round).
