Does the trial judge have authority to re-instruct the jury in accordance with the amended verdict form?

In the instant case, moreover, the trial court was not without authority to re-instruct the jury in accordance with the amended verdict forms. ( 1093, subd. (f) [trial judge may instruct jury members without any request from the parties on the law applicable to the case as the judge deems necessary for their guidance].) The trial court is obliged "'to clear up any instructional confusion expressed by the jury.'" (People v. Giardino (2000) 32 Cal.App.4th 454, 465.)
