I think you mean &&?

  No. && would cause the next command to begin once the previous had successfully completed. A successful install shoudn't start the next install attempt, hence ||. On the other hand, OP and this comment miss the beauty of Randall's implementation, which is each operation is launched asynchronously ('&'), so it isn't the case that you try a few approaches one at a time, i's that you try all approaches at the same time.
