A compound WHERE clause in GAQL?

Question

Could you please confirm GQAL doesn't support compound WHERE clause?

 FROM group_placement_view\
 WHERE\
    metrics.impressions >= 10000 \
    AND (metrics.video_view_rate < 10' OR metrics.average_cpm > 10000 )

and not event OR as non-compound clause?

    metrics.average_cpm\
 FROM group_placement_view\
 WHERE\
    metrics.impressions >= 10000 \
    OR metrics.video_view_rate < 10'
