Because the proximal surfaces of the molars are in a buccolingual relationship to the patient's sagittal plane, conventional image receptor placement parallel to the buccal surfaces of the molars often results in overlapping of the contact area and closure of the embrasure spaces.

The statement is incorrect. Conventional image receptor placement perpendicular to the buccal surfaces of the molars (i.e., parallel to the patient's sagittal plane) often results in overlapping of the contact area and closure of the embrasure spaces. To minimize overlap and obtain a clear view of the proximal surfaces, image receptor placement should be angled slightly buccally or lingually, allowing for open embrasure spaces to be visible.
