It has to be initialized as 2 lines (x16 multiplex mode). Otherwise the second line (right 8 characters in this case) is never scanned. Initializing a true 1-line display in 2-line mode doesn't hurt anything, but the contrast will be lower, and spurious pixels may appear on displays having 5x11 character cells rather than 5x8. Some types of 16x1 displays are true 16x1. These usually have 5x11 character cells for somewhat better looking lowercase characters.
