Yes this is often used in quilting but in quilting it is referred to as a set in seam or a Y seam. Most commonly used in the traditional piecing methods for:
Lemoyne Star
Lone Star (AKA Star of Bethlehem)
Tumbling blocks
Attic windows
Judy Niemeyer uses them a lot in her patterns as does Edyta Sitar. It is an invaluable skill to have in your quilt making arsenal.
