When VoiceOver speaks possible detected text, it is not displayed in braille on a braille display
The title says it all. While VoiceOver speaks the possibly detected text, there is no braille representation of this information. In certain apps, where this information can greatly improve access for speech users of VoiceOver, it leaves the braille only user without that additional access.
