Error "Pattern found in every line". I expect to get "Pattern not found"

On latest gVim development 9.0612 downloaded from https://github.com/vim/vim-win32-installer/releases/latest on Windows 10.

Text file:
aaa
bbb

Try to find out all values not maching "aaa"
:v/aaa/p
It outputs:
bbb

So far as expected. Now from text file delete line "bbb" so only line "aaa" exits.
Repeat last command:
:v/aaa/p
It outputs:
Pattern found in every line: aaa

Shouldn't there be:
Pattern not found: aaa

Just like at:
:v/ccc/p
Pattern not found: ccc
