I tried reproducing it with 
    cat >exclude-file
    mkdir -p d/x/ath_version1/bin/RCS
    mkdir -p h/x/ath_version1/bin/RCS
    echo hey >d/x/ath_version1/bin/cse_plot.csh
    echo there >h/x/ath_version1/bin/cse_plot.csh_shigeki
    echo guy >h/x/ath_version1/bin/RCS/cse_plot.csh,v
    ln -s cse_plot.csh_shigeki h/x/ath_version1/bin/cse_plot.csh
    rsync -av --delete --exclude-from=exclude-file --backup d/x/ h/x/ 
    echo you >d/x/ath_version1/bin/cse_plot.csh
    rsync -av --delete --exclude-from=exclude-file --backup d/x/ h/x/ 

Rsync changed nothing under "h" except for the timestamps of the directories.
Can you demonstrate the problem with a reproducible example?  What version
of rsync?  What operating system?
