Because the only case in which calculating range by simply counting the distance on the grid won't give you weird results that defy common sense is when you are using a hexagonal map.
That being said, I think that the value used for calculating the range via use of Pythagorean formulae is actually the range plus half a tile. That's a fairly common thing when you want to have an outer range area that is as close to being a circle as possible.
If that were the case, then with range of 3 you'd get 3,5 instead, which when multiplied by itself gives 12,25. And that means you'd be able to shoot at something that is 3 tiles in one direction and 1 in the other from you (as (3*3)+(1*1) equals 10), but not at something that is 3 tiles is one direction and 2 in the other (as (3*3)+(2*2) is 13, which is above 12,25).
Mind you, I'm not saying that this is guaranteed to be the case, but it is a rather simple and effective solution so I wouldn't be surprised if it was. If you want to make sure, you'd have to play with weapons that have different ranges to make sure.
