the problem is about "list"s and "anything"s.

the output on the second outlet of [niagara] is "list r 3 b 4" (and not 
"r 3 b 4").
now "route" will route messages according to their selector (in this 
case "list").

why does [niagara] output a "list" ?
if you send a "list" into [niagara] it will output a "list".
if you send "anything" (an undefined selector) to [niagara] it will 
(basically) output anythings (add some confusion: which might(!) be 

the simplest solution for you, would be to make sure, that you get rid 
of the "list" selector, by connecting the second outlet of [niagara] to 
a [route list] and then connecting both outlets of this to [route r]
