xingym Wrote:the action " flow" took place before the action " have been redirected" , so the verb tense " had orginally flowed" should be correct.

these 2 actions are in independent sequence -- neither one
affects the other -- so they should both be in the simple past.
for instance:
we went to the bar after we worked out --> there is no ostensible connection between these two activities -- they are just a random sequence of events -- so the simple past is appropriate for both.
james arrived after i had already left --> there's a connection here. the point is that my absence -- the fact that i had already left -- impacted the situation in which james found himself when he arrived. to show that kind of relationship, you use the past perfect.

MUCH MORE IMPORTANTLY
VERB TENSE IS A VERY, VERY LOW-PRIORITY TOPIC.verb tenses are
very difficult for non-native speakers (of any language, not just english) to learn -- much more difficult than just about any other aspect of the language.
fortunately, for this reason,
verb tense is almost never tested by itself; there will virtually always be
other ways in which to eliminate choices with differing verb tenses.
in general, you should not dedicate yourself to studying verb tenses until you can honestly say that you are 100 percent perfect at finding all of the more important error types (parallelism, pronouns, subject-verb agreement, etc.).
