Clustering uses sparse vectors by default. The missing coordinate values must
be zeros.

That is what I thought at first place.
But if you check the value of the 7th coordinate you will see that is 0.000.
This made me very confuse. It seems that it is still not presenting the
results on a sparse way.
A justification maybe that the value of the 7th is not zero but it was
rounded to 0.
I believe your thought is correct although I don't think it's precise to
assume any rounding. It may just be truncation for the purpose of displaying
the values. You might want to look at the code that displays your output to
see if you can increase the precision that's displayed.

+1 The formatting only prints the first 3 significant digits so any values less
than that will look like 0.000.
