A couple of things:
First, I was always of the impression that home heating oil was a lot closer to #1 than #2 diesel, therefore it would have a lot lower cloud point.
Second, there is no injection pump to protect, so it probably doesn't have nearly the filtration that a diesel engine does. Filters are typically what clogs up with wax crystals-if there's no filter (or a very coarse one), fairly cloudy fuel can be pumped (down to the pour point).
