Hip roof without a continouse hip rafter?

I have a rancher style house built in 2000 by a large builder. The roof has a ridge with hips on the ends (ridge is about 50% of the total roof length, the roof is 8/12 pitch). When looking at the interior of the roof from the open attic I see that the hip roof is made up of truncated trusses with short 2x4 wedged in the areas where the hip rafter would be. My question; Shouldn't the hip rafter be a continuous one piece or are the 2x4 sections put in place between the top edge of the truncated trusses acceptable?

Thank you for your help.
