I think "forcing users to use PayPal only" describes the behavior being examined reasonably accurately, though it is actually a proposal to force users to use only PayPal or cash on pickup.
The notification from the ACCC states that the notice allowing third-line forcing will be withdrawn, but allows a period for a response from any interested parties. The phrase "there is a period for appeals" reflects this accurately. The notice will be withdrawn unless there is a compelling new argument from eBay.
The title might indeed be misread as you have pointed out.
