Is a border hop required during the 180 days with a Thai Multiple Entry Tourist Visa from South Africa?

South African Embassy not issuing any visas currently and non immigrant retirement o-visas are not available to S.AFRICANS, only O-A. Embassyhere not responding to ph call or answering emails. One has to deal with VFSGlobal now. VFS Global offer S.A. Multiple Entry Tourist visa valid for entering Thailand once within six months from the date of theissuance of the visa. The period of stay is 180 maximum. My question is then, once in Thailand there would not be a need to exit and renter within those 180 days (border hop) ?
