yes, there is a difference between a hoarder and a disorganized person, or a person who just became overwhelmed. just because you have a lot of stuff doesn't necessarily mean you are a hoarder. sounds like this lady was using the stuff, it was just coming in faster than she could use it.
i don't like these programs because the host often goes in with it in mind that they know what is going on but in fact do not. their mind is already made up based on their perceptions. the outcome is not always the best for the people they are trying to help.
i did not see this show but imagine that he did his usual "you must limit to save your family" without any thought to how it got that way in the first place or has the family ever done anything to help her. sounds like her need to do this volunteer job got out of hand. maybe this will allow her to not take on so much next time. sure hope so.
