In my tailoring classes I took in High School, we had to do the "pull one thread" across to match up the straight of grain. I've been doing it like in the video for years, but it doesn't take me 3 minutes to do. The creased fold on the bolt is rarely on the straight of grain. If it's a hard crease, I will usually press the fabric to get rid of that crease before cutting. All you've got to do is hold the two selvages together and slide left or right until you see that it's hanging straight. I then pin my selvages together before placing it on my cutting matt.
