In the context of the script it does 
if hasq distclean $FEATURES; then
	CLEAN=1
	size="$(/bin/ls -lh  ${pkg} | /bin/awk '{print $5}')"
	einfo "Freeing up ${size} by removing ${P}${file_ext}"
	rm ${pkg}
fi

which would remove the package after it's done installing it. 
Being that we are only using a tmpfs this all sits in memory. So no need to keep a large distfiles tre hanging around chewing up memory.
I also implanted this feature in an /etc/portage/bashrc I posted to gentoo-dev titled "portage toys"

yeah? i defined it to use /dev/shm which I happen to mount rw on my
devs..
