Imagine you know that there are some repeating patterns in your dataset, e.g. heartbeats in an EKG. If you take two windows that happen to contain a heartbeat at the same position, the corresponding vectors will be close, and if the positions are different, the vectors should become more dissimilar the more the alignment is off.

Then if you create a number of clusters equal to the window size, you might expect that each cluster will correspond to one of the possible positions of the heartbeat within the window. But somehow that's not what happens...
