Replace eval with indirect parameter expansion, and you'll get what I think you want (although it doesn't match your current given output:

for high_item in "${high[@]}"
do
    arrayz="$high_item[@]"
    # arrayz is just a string like "low1[@]"
    for item in "${!arrayz}"
    do
        echo $item
    done
done

Note the need to quote the array expansion in the inner loop to preserve the whitespace in elements of low1.
