Easy to reproduce:
(1) Create a page with a normal user account. An entry will be shown in recent changes. You can use that to patrol the new page, for example.

(2) Move the page to a different name, but suppress redirect creation.

Expected: The link to the old page should be removed form recent changes.

Observed: The link remains in RC and is shown as a blue link (not a red link). The page will be shown as if it is not patrolled, and there's no way to get back to it and patrol the edit.

This causes confusion. Possible cause is that RC is not updated when redirect source is deleted through the redirect suppression mechanism.
