I'd say that your mechanic is kind of right in that brake shudder can be magnified by long reach brakes, thanks to the flex inherent in the longer brake arms, but the long arms are not necessarily the cause. Shudder is caused by irregularities in braking force--which cause the brake pads to stick to one part of the rim, flex the arm, and then jump back when braking friction is reduced. The same methods which you can use to stop a squealing or shuddering V-brake or canti brake apply here.
So the first thing I would try is making sure that your rim and brake pads have a nice, even surface with no irregularities. Clean off your brake tracks with some fine grit sandpaper to remove oil or other contaminants, and then wipe them down with a clean, dry rag. Make sure your brake pads don't have any pieces of metal or debris lodged in them, and then use a file to remove any glaze from the pad's braking surface and give it a nice, rough texture. I bet that takes care of it, since many others on here use the same brakes without issues. If it persists, maybe switching to brake shoes designed for v-brakes, with spherical washers that allow you to adjust the toe-in of the pad, might be in order.
