Indeed.
Also the automatic link to ESTA when scanning passports speeds up the process.
BTW: Just looking at the length of the line is not always a good indicator. If the waiting line is served by a large number of immigration agents with fast procedure (like in Hong Kong and even now the US), it will flow much faster than at CDG where they only open a few desks and control takes a very long time.
