Probably because excess calories from a fat source are the most likely to be stored in adipose tissue. Whereas carbs are middle of the road and protein the least.

As an ectomorph myself I find that I just build muscle very slowly. If I use a daily calorie surplus that typical for endo's and meso's I add too much fat. IMO a more conservative surplus and a longer bulking phase is probably the better approach for ecto's.
