What does it mean to break apart a standard clip?

Been checking out compound clips and I came across instructions on how to break apart a compound clip or a standard clip. Isn't a standard clip already an individual clip? What's to break apart? When I try it, all I get is a " - v1" appended to the clip name. Using FCPX 10.4.4. What gives?

Reference:

You can break apart a compound clip or a standard clip to convert its contents to individual clips in the timeline.

Select a compound clip or a standard clip in the timeline, then choose Clip > Break Apart Clip Items (or press Shift-Command-G).Final Cut Pro replaces the clip selected in the timeline with the individual items that made up the clip.

If you selected a compound clip, its contents revert back to the original clips that made up the compound clip. However, the parent compound clip remains in the browser.

If the selected clip is a standard clip, the contents appear as individual clips in the timeline. Most standard clips include a video component, an audio component, or both. The audio appears as a connected clip.
