The user will certainly interpret the text of the license as being a license.
The way I see it, you can include BSD or MIT code in your alter-licensed
product, and then license the whole/package/collection under the alter-license.
But each file originally licensed under BSD or MIT is still licensed that way.

Think of the book "Open Sources". It is copyright by O'Reilly. However, many
individual articles in it retain their own copyright.
