Yes. The one exception to this is when the licenses are compatible, but
not consuming. (Note: This is really rare. GPL/LGPL + anything ==
GPL/LGPL)

In some cases, it is possible for a binary to be generated from multiple
source files with compatible, but differing licenses. Thus, the binary
file would actually have simultaneous dual licensing (an AND, as opposed
to an OR). For example, it is possible that a binary is generated from a
source file licensed as BSD with advertising, and another source file
licensed as QPL (which specifies that modifications must be shipped as
patches). In this scenario, we'd wrap the list of licenses for that
binary with parenthesis, example: 

Package spot-utils contains some files under the Python License, but one
of the files is generated from a BSD with advertising source file and a
QPL source file. 

License: Python and (BSD with advertising and QPL)

Think about it like this:

If License A has a restriction on what you may eat, and License B has a
restriction on what you may drink, but they are otherwise compatible,
the resulting work would have both restrictions, and we need to reflect
that in the License tag.
