It is expected to have some degree of overlap between treatment populations, as this allows for the possibility of finding a significant difference between the groups through statistical inference. Without any overlap, it would be difficult to determine whether any observed differences are due to the independent variable or simply due to chance. Therefore, researchers typically expect and plan for some degree of overlap between treatment populations.
