If it's anything like the HD44780, lines 1 and 3, 2 and 4 are connected, respectively. It is seen by the controller as a 40x2 display, it's just separated into half of the first line to the controller is the 1st line, the other half, the third, and so on.

Just handle the writes accordingly and all should be well.
