Although not specific to your marginsplot question: It is a general
misconception and popular fallacy that confidence intervals should not
overlap if the difference is statistically significant.

See:
Cumming, G. & Finch, S. (2005). Inference by eye: Confidence intervals
and how to read pictures of data. American Psychologist, 60(2), 170-180.
