Following the exact "best practice" in the article, the iPhone lock screen has this issue. Say your password is 1234 but you accidentally type 11234. What the iPhone will do is see 1123, the pause to tell you you failed, then enter 4. Now you, having muscle memory, will type 1234 (your password). But iPhone kept that 4 so it sees 4123 then pauses to tell you entered the wrong password, then adds the 4, and you type 1234 again, which again it sees 4123.
Finally, frustrated, you pause and press delete or take some other action to reset the lock screen and this time it works.
This has happened to me countless times since iPhone had a lock screen.
The better UX would be to clear the that after the error which is effectively what the Nothing Phone is doing with the photo rotation
I agree 100% with the article that for photo rotation it should do what the iPhone is doing. Conversely, it's wrong thing to do on the lock screen.

In summary:
Record actions until interrupt.
Animation should not be considered interrupt.
An Error message should be treated as interrupt.
It's not that iphone keeps that 4; it's that iphone pretty quickly starts accepting the next round of input after 1123 and then you type 4.
Perhaps a longer pause will prevent you from typing that 4 but that also means other people who mistype their passcode have to wait longer to retry. It's a tradeoff. I suspect there are more people who type the wrong passcode of the correct length than the incorrect length.
