Sorry, I don't have an answer for you, I just found your problem
interesting. I've learnt some more bash!
I first thought that it might have something to do with a new process
being forked (like when you use ()'s) because of the | in loop 1. But
echo $$ sprinkled around shows this not to be the case.
However, this variant of your loop also works like Loop 2:
echo ===========Loop 3==============
declare -a RULEZ
i=0
j=4
# Read the test file line by line into the RULEZ array.
while read x
do
RULEZ[i++]="$x"
# Show what RULEZ contains
echo j=$j i=$i RULEZ has ${#RULEZ[*]} elements. ${RULEZ[*]}
done < /tmp/junkfile
echo j=$j i=$i RULEZ has ${#RULEZ[*]} elements. ${RULEZ[*]}
