Worst case scenario:
two sysops go on an edit war. against each other. They lock the page, to no avail because the other can still edit it. Then one bans the other other's IP. The other retaliates by blocking the account.
This is only possible in the case of a very few people who have login access to the server for development and maintenance. In general, sysops cannot identify the IP address of a logged-in user, nor block a user account.
