A question about "PlayQueueSample"

I tried the "PlayQueueSample" (https://docs.unity3d.com/Manual/Playables-Examples.html - the last one) with a lot of AnimationClips from different sources, and it seems that while it plays clips one after the other, the starting position of the next Clip doesn't match the end position of the previous.
To make it a more confusing, i found one example, where it is correct on the first, and only on the first play. However, when it starts to play the queue again, the starting position is not what's expected, it teleports the character back on the Z axis, more and more to negative Z each time it's playing.
Any thoughts...?
