Yes, same stuff - it comes in braided and twisted. The twisted variety can be separated into smaller threads as well. Braided is usually stronger at the same diameters, less likely to fray or unravel at the ends or from partial thickness cuts and abrasions, more symmetrical, and ties/holds knots better (although with the tar embedded, that's a moot point).

Dave Canterbury has heavily promoted the use of bank line even over paracord for most applications. Although it can be used for tie downs for tents/tarps, I prefer to use hi-visibility guy lines like Kelty triptease because I'm bad for tripping over them!
