the feature kicks in at different shutter speeds depending on your ISO setting. According to the manual, on ISO 1600 it's on exposures 1" or more, less than that (ISO 800 - 100), it does wait until the 30" mark (p. 148).

So it may or may not have been the cause depending on how long your exposure was. Otherwise, I'll go with what Seltzer said
