Two sample t procedures are used when subjects in one sample are completely unrelated to the subjects in the other sample. This is because the purpose of the procedure is to compare the means of two independent populations. If the subjects in both samples were the same, then it would be a paired t-test instead of a two-sample t-test. Similarly, if the subjects were similar in both samples, it can also be a paired t-test or a one-sample t-test.
