A tritone is half an octave, so cycling through chords separated by a tritone means just alternating between two chords, in this case C and F#. The contrast between the two is significant, so it may not be what we'd think of as ambient if it occurred just sometimes at random, but since here it's happening constantly, it becomes part of the texture and doesn't hold listener attention.
