As far as I can tell, neither checkin explains why this behavior was
added.
Hyatt's comment on the WebKit checkin says it was to match other
browsers (presumably Mozilla).

In Internet Explorer 7 and Opera 9.5, if the document later contains
the usual comment terminator, then that character sequence terminates
the comment instead:
http://crypto.stanford.edu/~abarth/research/html5/comments/strange-ending-with-real-ending.html
http://crypto.stanford.edu/~abarth/research/html5/comments/strange-ending-with-later-comment.html
Firefox 3 and Safari 3.1 do not appear to exhibit this behavior.
(Interestingly, the syntax highlighter in vim suggests the document
will be parsed as in Firefox and Safari, no doubt contributing to
author confusion.)
