I'll be charitable, and suggest that your trainer is "giving the customer what they want". However, the fact remains that using an arm ergometer will NOT reduce arm fat.
Fat is not directly usable by the muscles. When your body detects energy reserves are low, it releases a hormone that detaches some of your existing fat stores (from all over the body). These are processed in the liver into a form of energy called ADP, which is then carried by the bloodstream to whichever muscles are demanding it.
The significance of exercise is not that it is burning fat in a particular spot, it is that it contributes to an overall calorie deficit.
Perhaps try asking your trainer about the "spot reduction myth", and see what they say.

Your arm ergometer workout may help increase the endurance of your arms. However, I would not expect any improvement on the bingo wings. For the fat in that part to go away, as M@L pointed out below, you need to reduce your body fat %. You might still find that there is an excess skin problem, which is harder if not impossible to take care of without a surgery.
But burning fat is an all-body process, and you can't target where you lose weight from. Energy is delivered to the muscles via the bloodstream, NOT from being absorbed from surrounding fat stores. An arm ergometer will NOT reduce arm fat.
While an arm ergometer is a great way for people with limited mobility to get in cardio exercise, generally speaking, you are better off using your legs for cardio, as they are larger muscles capable of burning more calories.
