More like a lookup table of nodes.  The match=
specifies the node in one column (say "left
column"), and the use= specifies the lookup value
in another column (say "right column").

One then uses key() to return all nodes from the
left column whose corresponding lookup value is
the right column is the second argument of the function call.

There are drawings on this page that may help:

I hope this helps.
