From what I can gather it seems Lloyds family were willing to continue their relationship if he didn't disassociate (for his father in particular), and for his sister if he discontinued his very public activism.
If so, that's an example of the crony system they have - other people are deemed to have disassociated by their actions, without sending in any letter (as people imagine they have when they announce it)
But if daddy is an elder, you are treated very differently.
Lloyd isn't fighting against the system, he's part of the system, making full use of the double standards and varying rules based on who you know or are related to.
I think every hall had those vile spawn of vile elders who just oozed corruption.
