Sorry, but think 'the coin does not drop'. This even a picture of a part of y'r link. Visa and workpermits are 2 different things. If people want to work in Thailand first they must have a visa to stay and THEN they must arrange a workpermit. If you are not married to a Thai, you need that non B visa indeed but because you have a visa with which it's also legal to work, you only need a workpermit.
