If you have new messages, two links are given. One for your talk page in general, and one for a diff view.
On a revision comparison (diff) for your own talk page, the new revision should be auto-patrolled.
There is no need for sysops/patroller to patrol most of talk pages of others then anymore.
Maybe also auto-patrol the revisions of the user talk page that are "manually" checked by the user itself from the history page (diff). And maybe not just for the talk page...
This extension is currently unmaintained, and no fixes should be expected in a foreseeable future.
Most likely, this bug report will end up as a WONTFIX later this year (per Andre).
