While all of that is true, the fact is that the MyBB default CAPTCHA does not prevent spam registrations. It gives the appearance of security without actually providing any.
Case in point: the MyBB 1.9 demo was using the default MyBB CAPTCHA until I discovered a large number of spam registrations coming in. I switched to reCAPTCHA and the spam registrations stopped immediately.
