When backtacking, the machine will stitch in reverse direction into the same stitch holes. The sketch shows stitches and direction. Angles are only used for better understanding:

Machines in the middle and high price range normally come with electropneumatic seam backtacking assembled as serial equipment. However, a lot of more simple models can be retrofitted with this additional equipment which will make them more valuable.
