Two tape marks is just a convention used by some

standard ANSI formatted tapes can legally contain two consecutive tape

indicate EOT.
Old tapes are extremely variable on their use of ANSI labels, so when
archiving, I'll read as far as possible (i.e. either to EOT or a "blank
media" exception.
And then there's Unix/Linux and many other OSes that don't give a fig
about ANSI labels.
