True. The analysis of the sequence of intersecting strokes (lines) is indeed called **stroke sequence analysis** or **line crossing examination**. This is a challenging aspect of questioned document examination that seeks to determine which of two intersecting ink lines was applied first. The examiner uses a stereo microscope, often with oblique lighting, to look for subtle physical evidence at the intersection. When a ballpoint pen line is written over a still-wet line, the second line may show a slight 'skip' or interruption as it crosses the ridge of the first. If the first line is dry, the second line may travel on top of it without interruption. Techniques like ESDA can also be useful, as the static charge may interact differently with the indentations. Determining stroke sequence can be critical in proving document alteration—for example, showing that a signature was written *after* the text of a contract, suggesting it was added later to a blank sheet.
