They're completely unrelated; \hcenter doesn't `need' column, it's
used to align an object to its centre *relative* to another object.

The example for \hcenter in B.8.2 uses \column as a convenience to
show the alignment relative to the arrow.

This doesn't work, since \hcenter comes before \column; it has no
reference point to work with. If you swap them round, this behaves
just like \center-align.
