don't understand why should I not move the settler?
One turn of doing nothing is not good as others are doing something. Civ starts are usually balanced, you should get at least something in the Big Fat Cross (BFC we call it here). Your civilization is progressing exponentially, and one turn lost is a lot. The only justification for wasting a turn is if you are sure that the new location is better than SiP (Sit in Place). Then your initial base value (food, hammers, commerce yields) is higher and you will catch up with the lost turn. It is helpful to see stuff mathematically for this game.
this would be the initial start, moving my warrior to the SE.
I'd say that you moved SW the way the warrior stands and what is visible. You revealed 2 tiles at best.
