It's not even stair running. The OP said it was a machine, which the OP is hoping to encourage his wife to use. Will it help his "peddling [sic] strength"? Sure. Is it as beneficial as actually riding his bike? Doubtful.

BITD we would have pedaled a flat time trial at a high cadence concentrating on spinning. Any upstroke would have been minimal and somewhat incidental, perhaps about equal to the weight of your foot/leg assembly. This is exactly what the study shows.
Real roads are not always dead flat. When climbing, the slope can vary over short distances. Pulling up allows you to increase your torque and get through a steep section without shifting gears. Granted, this was more of an issue in the past when we had fewer gears for climbing (and friction shifting). For the same reason (no low gears) people used to climb out of the saddle more than they do now.
Another situation where upstroke comes in is when riding on slightly rolling terrain. If you get to a small rise, say 100 feet or something, adding some upstroke makes it easier to kind of turbo over it, and maintain your velocity.
Lastly, varying your stroke lets you shift your working muscle groups around a bit, which can be helpful in giving them a bit of a break on a long climb or whatever.

RE the OT
Strictly speaking, a stairmaster type machine won't help your cycling strength as much as the same time spent cycling. However, if the machine gives you a convenient ability to workout when otherwise you wouldn't have, it will help.

If you're riding at or below threshold most riders have between 15 and 30kJ of anaerobic work capacity to be doled out when necessary. That's enough for an extra 100W for 2.5 to 5 min or 300W for 50 to 100 Seconds.
I think if you have underused muscles your pedal stroke is probably sub-optimal. Ideally, all of ones muscles (used for cycling) should fatigue at similar rates.
