Focus order behaviour for Non-Modal mentioned in ARIA 1.1

Hi Team,

I feel that there is inconsistency between the point mentioned in aria
1.1 and the point in wcag  2.0 regarding the focus order behavior for
Non-modal dialog.  From WCAG 2.0 I understand  that, From the last
interactive control within the Non-modal, the tab focus can go to the
next  interactive control in the page which is out of the non-modal
dialog.
If there is any change in the behavioral pattern updated in aria 1.1.
or, if I had mis  interpreted the points, please kindly help me
understand.
Below I have given the relevant points and their links.

WAI-ARIA Authoring Practices 1.1
https://www.w3.org/TR/wai-aria-practices-1.1/#dialog_modal

Under the heading: 3.8 Dialog (Modal)
(Like non-modal dialogs, modal dialogs contain their tab sequence.
That is, Tab and Shift + Tab

do not move focus outside the dialog)

Understanding Success Criterion 2.4.3 | Understanding WCAG 2.0
https://www.w3.org/TR/UNDERSTANDING-WCAG20/navigation-mechanisms-focus-order.html

Point 2 below the heading: Examples of Success Criterion 2.4.3
(2. A Web page implements modeless dialogs via scripting. When the
trigger button is activated, a

dialog opens. The interactive elements in the dialog are
inserted in the focus order immediately after the button. When the
dialog is open, the focus

order goes from the button to the elements of the dialog,
then to the interactive element following the button. When the dialog
is closed, the focus order

goes from the button to the following element.)
