I haven't found clear spec evidence of this behaviour but this is
expected by a conformance test that changes the value with
glProgramParameteri but does not link the program. Test says:
"The query for PROGRAM_SEPARABLE must query latched state. In other
words, the state of the binary after it was linked. So in the tests
below, the queries should return the default state GL_FALSE since the
program has no linked binary."
