I've never been convinced it's a good idea to have such templates: it's hard to make sure that the entry conditions are the same whether it is invoked by apply or by call. In particular, when you are writing a match template it should be possible to assume that the context item matches the pattern, and allowing entry by name makes this assumption invalid. I agree that it is probably not such a great idea. I have had occasion to do it, but it's also been suggested to me that in such a case, an extra step of indirection to avoid it would make the traversal much clearer (as Mike also suggests) and maintenance easier. So I might have changed my mind. And in this case, the very fact that you need to test which way the template was entered suggests it's not such a great idea.
