          * Determines whether the given node needs to be parenthesized when replacing the previous node.
+         * It assumes that `previousNode` is the node to be reported by this rule, so it has a limited list
+         * of possible parent node types. By the same assumption, the node's role in a particular parent is already known.
+         * For example, if the parent is `ConditionalExpression`, `previousNode` must be its `test` child.
          * @param {ASTNode} previousNode Previous node.
          * @param {ASTNode} node The node to check.
          * @returns {boolean} `true` if the node needs to be parenthesized.
