Yeah, that strikes me as very un-Apple-like. Since OS X first came out, they have only ever released ONE update after the next major release came out (10.4.11,) and that was less than a month after 10.5's release. 10.2.8 and 10.3.9 each came out less than two weeks before the next major release; but no updates after.

Once a newer version is out, point-releases for the previous versions stop. Only individual security updates continue; and even those stop once the next major version comes out. (For example, security updates for Tiger will almost certainly cease when Snow Leopard is released.)

What's odd is that the article makes the claim; but I have never seen any such rumors. Not on LEM, not on MacRumors.
