I believe this is because the Mac tries to detect what kind of display is attached at power-up. With none attached it shuts down the video display and weird stuff starts to happen. With the DVI to VGA adapter the Mac can still tell when there is no VGA display attached because VGA also has sense pins for the type of monitor. The DVI to Composite (or SVideo or NTSC/PAL) can't tell if you have something hooked up or not so it gets past this issue with Mac screen detection.
