We need to memmove 11 bytes, otherwise `buffer[10]` ends up as a copy of `buffer[9]` which resulted in the second byte of button state being wrongly re-used as a third byte as well.
The original code did not suffer from this - while the length check was also one off, and likely informed the one off memmove, the buffer pointer was just incremented so everything "moved" correctly.
