It will redirect to the new directory

testdirectory

Which means previously created directory.Actually what it means, I don't know really

The duplicate question is not really an answer to this one. It can be derived from that, but IMO that's not the same thing at all. — Raydot, Oct 12 '19 at 17:39

$_ means the last argument to the previous command.

Example:

echo "FOO" "BAR"
FOO BAR
echo $_
BAR
