The templates depend on coordinating pre-defined views of particular names with matching names in models in order to place and orient the views. I'm not sure what happens if there is no match.
After the drawing is created there is no guarantee that on any particular drawing the views in one model would match those in another, even if the names matched. When it happens, it's a special case. It's similar to why it's not possible to simply go to the model tree and simply edit a part name as a simple way to simply substitute a new part. Seems like it would simply work for simple things like washers and bolts and nuts, but it simply isn't simple at all.
I think if one was careful one could use templates, but I never ran into users who were so fastidious that they would make sure the Front view was always something sensible, so I typically ended up deleting template driven views.
