I'm not sure I fully understand the question and the context. But maybe this works:

#!/bin/bash
foo="$(realpath "...")"
bar="$(realpath "...")"

if [[ $foo = $bar/* || $bar = $foo/* ]]; then
    echo "Overlap"
fi

foo="$(realpath "...")"
bar="$(realpath "...")"

if [[ $foo = $bar/* || $bar = $foo/* ]]; then
    echo "Overlap"
fi

Note that this won't work if one tree is sym-linked into the other.

foo & bar are results if realpath

I'm not sure I fully understand the question and the context. But maybe this works:

rd1="$foo="$(realpath "$foo""...")"
rd2="$bar="$(realpath "$bar""...")"

if [[ "$rd1""$foo" = "$rd2"*"$bar"* || "$rd2""$bar" = "$rd1"*"$foo"* ]]; then
    echo "Overlap"
fi
