Typographical error in page

I believe there is an error in the page at http://www.meyerweb.com/eric/css/inline-format.html. About 2/3 of the way down the page where the text addresses replaced elements it reads:

<P style="line-height: 12pt; font-size: 12pt;">
<IMG SRC="filler.gif" style="height: 120pt; width: 16pt; margin: 8pt;"> 
angry text 
<B style="vertical-align: top">bold</B>
</P>
The total height of the image's content-area is 136pt (128pt + 8pt + 8pt)

Shouldn't the total height of 136pt be 120pt + 8pt + 8pt since the image height is 120pt? If not, 128pt + 8pt + 8pt = 144pt. But where would 128pt come from?
