I think this is the correct definition, considering that V&V are Verbal fabrications, rather applied and sustained attention (ringing and reverberations of bell similie- is that from the Visuddhimagga?). Adverting to each jhana factor it is possible to experience each one separately. In this the discursive thought-like nature of vitakka and vicara manifest clearly. Visuddhimagga I think differs from this, if I am not mistaken, hinting at the scholarly hand behind the manuscript of practice.
