[Piglit] [piglit] should error be generated in spec/ARB_occlusion_query2/api

I have a question about "spec/arb_occlusion_query2/api.c", in function test_error_end_wrong_target(), it goes through the following sequence.
When the second glBeginQuery() is called, it expects GL_NO_ERROR to be generated afterward, but I think GL_INVALID_OPERATION should be generated.
See 4.4 core profile spec, October 18th 2013, p.41. it says:  An INVALID_OPERATION error is generated if id is any of: the name of an existing query object whose type does not match target or an active query object name for any target and index.

    static bool test_error_end_wrong_target(void)
        glGenQueries(1, &oq);

        glBeginQuery(GL_SAMPLES_PASSED, oq);

        glBeginQuery(GL_ANY_SAMPLES_PASSED, oq);
        if (!piglit_check_gl_error(0))
            pass = false;

        glDeleteQueries(1, &oq);

Best Regards!
