Re-entering USA on H1B (COVID)

I am on an H1B (non-immigrant VISA), in USA since 2018.

If I understand the current ban correctly (signed Apr 22), if I leave the country, I would not be allowed back in because of COVID (only Americans and LPRs can enter).

Is my understanding correct?

Your understanding is completely wrong.

The current ban is only for immigrants and not for visa holders. H1B is a nonimmigrant visa.

New bans for H1B may be placed on visas in coming days but as of today, there is none.

Thanks for responding.

The person who works on immigration at the office also read the DoS post and thought what I thought, but based on what you are saying, we must be wrong. Where could we check?
