Savile Row convention is to put a buttonhole in both lapels for symmetry, though not all Savile Row tailors do it all the time. Off the row, the practice is less universal and some tailors do just one since you would never wear two flowers. To the extent there is a convention about this, it is a very low power convention and if you have your own preference for one way or the other, there is no reason not to follow it.
