I believe it counts the distance, but it’s a straight line from one signal to the next. So it’s not nothing, but it’s not accurate either - just the best guess it can make with what it’s got.
(eg, in OP’s screenshot, the example at 9 o’clock. You can see the dots don’t follow the path, at all - they just make a beeline between the two readings it is confident in)
