When you call append_branch() or loockup() (and various contacts are
retrieved) the cfg script continues normally. At this point its not a
good idea to inspect the $ru neither $du or bflags as you would find
values for just *one* of the loaded contacts/destinations. Which one?
maybe the last element retrieved from the DB, no idea...

So the cfg script continues. Then at some point you call t_relay (and
you set on_branch_route("N") before). So you get into branch_route[N]
block in which you process each generated destination in an
independent way, so into this block you can inspect $ru, %du, bflags
per destination.
