With most guitar strumming and picking techniques, the bass note is the first note that gets played in the context of the chord and the rhythm within a song.
Therefore, whenever possible, it makes sense to prioritize getting that note placed first, and letting your other fingers follow closely behind. VERY closely behind.
Important: in some of the demonstrations in this set of lessons, I move my "bass note" finger first, and pull my other fingers out of the way so that you can clearly see what I am doing.
However, that "pulling away" motion is for demonstration purposes only!
Ultimately, you always want to keep your fingers as close to the fingerboard as possible, and watch NOT to develop a habit of letting them pull away from the neck. That will only end up costing you time, and orientation, as you go.
