Yes, that's what I get when I shortcut MOSI and MISO on the ISP plug
of my programmer (i. e. with the AVR target disconnected):

bitbang_cmd(): [ AC 53 00 00 ] [ AC 53 00 00 ]
bitbang_cmd(): [ AC 53 00 00 ] [ AC 53 00 00 ]
...

When I connect it to an ATmega48, it looks like that:

bitbang_cmd(): [ AC 53 00 00 ] [ FF FE 53 00 ]
