From the source:

There is also a secondary progress displayable on a progress bar which is useful for displaying intermediate progress, such as the buffer level during a streaming playback progress bar.

One can find a fully worked example of displaying such a bar, including screenshots of the appearance of such a bar in a particular style (circular bar which fills from the bottom):

Secondary Progress Bar

In the image above, the secondary bar is the green area, when it reaches the top, some subtask is complete.

  • Thanks @AlaaM. - I added one of the links to the answer with a screenshot. – BeeOnRope Jan 20 '17 at 17:22
  • A common example if your daily life is video streaming. The primary progress is the current playing time of the video, while the secondary progress is the downloaded part of the video. – Sira Lam Jun 05 '19 at 07:40

Secondary progress vs Progress can be thought of like the downloaded part of a video you're watching vs the complete length of the progress bar
