It's not confusing. In a class action, all shareholders are contacted.
If one or two individuals hire counsel to represent only their interests, that's who the lawyer(s) work with, that's who gets contacted and updated, and that's who gets paid in a settlement.
There is nothing "similar to class action." It's either class action or individual lawsuits. Anyone can opt out when they're contacted by the lawyer hired to represent the class if they don't trust the representatives for the class and hire their own lawyer to protect their own interests.
