I don't think that is true Mayea. Although I have heard that you get better hip rotation on a arc trainer versus an eliptical and recruit more muscles into the workout. Choosing equipment really lies in your goals and physical limitations.
Elipticals are smooth machines and great for people who are looking to have less impact on joints. Better to use an eliptical regularly then to use a treadmill that causes you pain and give up. Problem I see though is that most people don't maximize the use of elipticals. The way I would use it is for
Fat Burning "Interval Training."
Most people assume if they get that Eliptical up, and crank out a high intensity 30 minute session then they are burning fat but not nescessarily. Continous High Intensity actually stimulates Muscle Tissue, ie burning Glycogen. So you drip sweat after 30-40 minutes, and you assume that you really burned alot of Fat. Well maybe some, but more proportionatly Glycogen, and not energy from Fat.
When engaged in High Intensity the body would rather burn Glycogen, as this is more easily converted to fuel, and can be easily reconstituted by simply drinking something like Gatorade. The body knows that if it burns fat it is a timely process to put it back on. The body likes to save it's fat. To get the body to Burn Fat, a moderate pace, with sporatic High Intenasity Intervals training works really well. If you don't have joint issues I do think the Treadmill is better suited for this type of interval training but it is doable on an eliptical.
To achieve Fat Burning on the Treadmill, start out with a modest pace then after a 2-3 miniute warm up increase speed level slightly to say 3.0-3.3 for 1 minute, (longer if you are not in shape), then increase to say level 4-4.5 and jog fast for 60-90 seconds (shorter if not in shape), then go back to say 3.0-3.3 range for another 1-2 minutes. After another minute or so of walking, Jog again, do this hi-low stagger for the first 10 minutes. Then for the next 10 minutes elevate the ramp to keep heart rate at target, as 20 minutes approaches, lower ramp, then increase speed level and jog run for at least 1 minute no more than 2.
Bring speed down to 3.0-3.3, walk for another 5 minutes minimum.
The body seems to not really burn fat untill the 20 minute mark, all you are trying to do is keep your heart rate in target range. At the 20 minute mark the fat burning begins, so then "At 20 minutes why don't I sprint flat out for 5 minutes?", because it will shift focus onto muscle stimulation, & lactic acid production, BURNING GLYCOGEN FOR FUEL, instead of Fat. You feel you are accomplishing something, your improving heart condition, but not as effectivly burning fat.
Again, it goes back to what are your goals for this work out.
It would seem logical that flat out high intensity would burn fat, yet when you see how it is the body utilizes energy it is really the Moderate to brisk intensity that actually burns fat.
Ok.. I went on a tangent but I think I answered your question... lol
