I get the same result here with IE8 in Vista, the saved files are marked for
indexing.

I was able to reproduce the OP's symptom however by saving the file into a
Folder that did not have indexing enabled. I turned indexing off in the
folder for the experiment. While indexing was turned on the files saved into
the folder from IE8 were also flagged for indexing. When indexing for that
same folder was turned off a newly saved file had indexing disabled.
Re-enabling indexing for the folder automatically set the indexing flag on
the previously saved file as well.
