Resolution Note:
This is expected behavior. When a clip is mirrored in a blend tree, the clip is also offset to ensure that the footcycle is the same, so that the clip can be properly blended with other clips. In the case of the clip Base_Run01, the clip is symmetrical except for the footcycle, so the mirroring operation seems to not have any effect. To see the effect, try using a clip of a character running and turning at the same time, you will see the turning direction be mirrored, but the footcycle will be the same.
The documentation will soon be updated to clarify this behavior.
