Not necessarily, since there's another capital 'T" in the word 'That' found later in the same sentence.
Both 'Thats' follow a dash, a punctuation mark seldom used today, so I'm unclear what it's supposed to mean.
However, the second 'That' and its dash are preceded by a comma, and to my mind if the first 'That' was intended to also be part of the same sentence, it would also be preceded by a comma.
A quick look at the Declaration will show clearly that capital letters are used a lot more frequently and apparently randomly than they are today.
Would you care to repeat that?
