You know, I mis-spoke and forgot about this. My folks had an old Nissan Pathfinder with an indepedent button for "power" and "economy" in addition to the O/D on-off. Power-mode would rev the tach higher between shifts, shift harder, and was automatically engaged with a switch in the floor, under the gas pedal, for WOT "emergencies". (we all hated to drive that vehicle, ugh).
Many cars have a "normal" and "power" transmission selection mode so the car will behave in a performance manner under the power-mode. Nissan may have rolled all of this into the O/D off switch. Not only would you stay out of top gear, the transmission might shift with performance in mind. Much of my experience was limited to Fords, which, for the most part, had a fancy way to shift the column down to "3", with the press of a button.
The next time I rent a Nissan, I'll have to mess with the O/D switch (which may be tomorrow).
