 How permissions apply may at first seem intuitive, but there are some hidden restrictions that prevent bots from performing certain inappropriate actions based on a bot's highest role compared to its target's highest role. A bot's or user's highest role is its role that has the greatest position value in the guild, with the default @everyone role starting at 0. Permissions follow a hierarchy with the following rules:
 
-* A bot can grant roles to other users that are of a lower position than their highest role.
+* A bot can grant roles to other users that are of a lower position than its own highest role.
 * A bot can edit roles of a lower position than its highest role, but it can only grant permissions it has to those roles.
 * A bot can only sort roles lower than its highest role.
 * A bot can only kick/ban users whose highest role is lower than the bot's highest role.
