Why the constructors chose to go with this "auxiliary bridge" routine
one can only guess at.

Pure speculation on my part, but there is still a fairly large volume of
good size container shipping passing under the bridge. Maybe, just
maybe, this approach lets the lifting barge get out of the way sooner as
they only need to get it onto the support bridge and don't have to stay
there hold up the section while the support cables are installed.
And maybe given the size of the sections and height, there might not be
two such lift barges available to keep the load balanced?
