> I'm finding this a little confusing as it looks like BTC blockchain addresses can also be Tether addresses. Is this correct?

Yes. Tether is so-called Smart Property (with Property ID 31) stored using Omni Layer. Omni Layer stores transactions on Bitcoin Blockchain. Transaction data is encoded as output script, which uses OP_RETURN opcode and zero value. OP_RETURN opcode allows 80 bytes of data. Omni Layer uses 4 bytes ("omni") of 80 as a prefix to coexist with other systems using OP_RETURN.
