May not be the same type of construction , but several homes that meet that description collapsed during the 1994 quake in Northridge.
I know because a friend of mine owned one.
Seems like a design that would be prone to failure during large quakes to me.
I would rather own something bolted to a slab foundation that is either on flat land or not backing to a downward slope, backing to an uphill slop I think would be more indicative of a cut lot.
