I believe the answer is ‘it depends’ and it can be nearly unlimited. There is no ‘usually’.

Your sample song is short and has two simple chords. On a song of more typical length, say, 32 or 48 measures with three choruses, and with more complex chords, you could regenerate all day long and maybe not get an exact duplicate track for the entire song. Yes, you will often hear the same or similar phrases, but it will not be the same over the entire song.
