Can a witness be cross-examined during cross-examination?

Under Evidence Code section 772, a trial court may, in its discretion allow a party to "interrupt his cross-examination, redirect examination, or recross-examination of a witness, in order to examine the witness upon a matter not within the scope of a previous examination of the witness. (Evid. Code, 772, subd. (c), italics added; People v. McDermand (1984) 162 Cal.App.3d 770, 792 [all phases of examination of witness need not be concluded without interruption].)
