These concerns make sense if we assume that they have no processes. My understanding is that they are using holocracy, so there are defined processes each with leaders (like boards with a chair) and these process are organized in a hierarchy that allows some to be overridden/replaced/reformed by boards with more central power. So, people can and should try to have many roles but will naturally get pushed out of things where they lack time, knowledge or trust, and not everyone is involved in every process or is allowed to nominate themselves to be involved.
