In the AdventureWorks2014 database, the view vSalesPerson returns 17 records having phone numbers wherein the last 4 digits all begin with 01, e.g., 615-555-0153, yet the Chapter 10 phone number profile patterns don't recognize these as constants. The (12 character) pattern is given as \d\d\d-555-\d\d\d\d rather than \d\d\d-555-01\d\d. Does anyone know why this occurs?
