Yeah, makes us uneasy too.
Our next door neighbor had a house built 30 years ago. There is a roof section that slopes to a vertical wall. There is a slight downward slope along the wall, as well. When he was building the house I chatted with him and he told me the builder insisted that a roof full of water ending at a vertical wall would be fine as long as he sealed it correctly. I guess he didn't do that because it was repaired about 10 years later. Then again 10 years ago the vertical wall was stripped inside and out and replaced along with the lower part of the roof that sloped to it. It all still slopes in the original fashion just with new studs and roof rafters and so on. I figure it will happen again in another year or two.
My basic model is that if it looks like it's a dumb thing to do, I wouldn't do it, even if an "expert" says it will be fine. And, "multiple layers of treated lumber, sheathing, wrap and a waterproof barrier under the siding" just sounds like a dumb thing, to me.
