"having no Se" means to not have it in the ego, nor valued. ESEs deal with Si, it forbids them to push people into wtv is the mood of the environment, else they would alienate their duals, who'd join the environment only if really interested in it, and not out of a threat (Se polr). Se push can be delivered in many ways, using it to establish a power hierarchy is not Si valuing.
