The way I read it is that they don’t allow (travel agents) to open anything. If your ticketed booking class isn’t available, they can rebook you in higher inventory up to H but not above. If that results in no flights available, then I guess you have to take the refund or they have to escalate to American for a waiver code. That little section I quoted above was for basic economy tickets.
