No, rev matching is bringing the revs up to where 'they will want to be' when you release the clutch in the new, lower gear. Blipping is a poor substitute for rev matching but is considered acceptable when heel/toeing. p.s. If you ever drove a car without synchromesh you would learn that rev matching has to be more accurate than just blipping the throttle. Of course, today with all manual transmissions being synchronized blipping has become adopted as rev matching because it requires less skill.
