Your lens dates back to a time when some lenses were still completely manual, and the aperture had to be manually closed for stop down metering.
Your zoom lens has a more modern feature that allowed for wide open metering and then the lens would automatically stop down to the desired aperture just as the photo was take. By the 1970’s most lenses had this feature and they were called “auto” lenses.
That’s why it is called “Auto-Zoom”.

Auto refers to the aperture control, as Mike Sowsun describes. Zoom refers to the ability to change focal length.
