Trying to clarify if what I have read applies to all Origin 20H amps.

I purchased a used Origin 20H.  The back of the head looks exactly like the picture in the slideshow on the Origin 20H webpage.  One 16 ohm out put and two separate 8 ohm outputs.  I have read a few different posts on various forums regarding the correct/incorrect labeling of these outputs on the Origin 20 amp heads.

So my question is...  Are the output jacks on my amp labeled correctly(one 16 ohm and two individual 8 ohm jacks) or should they have been labeled as I have been reading that when using both jacks 2 and 3 that only two 16 ohm speakers/cabinets should be used?

On the serial number tag there is code 05-18 which I assume means that the amp was manufactured in May 2018.
