HTML 4.01: "Calculating the width of columns", first example

Hello,

I'm seeking help in understanding the text accompanying the first example in HTML 4.01, Tables, Calculating the width of columns.

http://www.w3.org/TR/html4/struct/tables.html#h-11.2.4.4

The text says:

--quote--
[...]
The table in this example contains six columns. The first one does not belong to an explicit column group. The next three belong to the first explicit column group and the last two belong to the second explicit column group. [...]
--quote--

The example this text refers to reads:

--html--
<TABLE>
<COLGROUP>
   <COL width="30">
<COLGROUP>
   <COL width="30">
   <COL width="0*">
   <COL width="2*">
<COLGROUP align="center">
   <COL width="1*">
   <COL width="3*" align="char" char=":">
<THEAD>
<TR><TD> 
...
...rows...

</TABLE>
--html--

Why does the first column of this table not belong to an explicit column group? It is a child of a <COLGROUP> element and therefore I'd consider it part of an explicit column group. Isn't this the case?

(The errata do not have an entry concerning this issue.)
