Sigh... Unfortunately I am not confused and am tired of explaining. But I'll try again:
subsequent adjective the subsequent months: following, ensuing, succeeding, later, future, coming, to come, next. ANTONYMS previous.
Unionequityinc.com as you explain came before https://who.is/whois/worldcurrencyandmetaltraders.com so by definition the new domain is a subsequent domain. It was bought in the same goddady account who's data has been unchanged.
Godaddy itself says it is no big deal and usually an oversight if unchanged. Non issue
