A confidence interval using the repeated-measures t statistic is used to estimate the mean for a population of difference scores, not just a sample. This approach is typically used in within-subjects designs where the same subjects are measured under different conditions, and the interest is in estimating the mean difference in scores across these conditions for the entire population from which the sample was drawn.
