Add three 3-dimensional vector groups together?

Rewriting the 3-dimensional example this is what I get:

In[1]:= {1, -Sqrt[2], 1} E^((-2 - Sqrt[2]) t) + {-1, 0, 
   1} E^(-2 t) + {1, Sqrt[2], 1} E^((-2 + Sqrt[2]) t)

Out[1]= {-E^(-2 t) + E^((-2 - Sqrt[2]) t) + 
  E^((-2 + Sqrt[2]) t), -Sqrt[2] E^((-2 - Sqrt[2]) t) + 
  Sqrt[2] E^((-2 + Sqrt[2]) t), 
 E^(-2 t) + E^((-2 - Sqrt[2]) t) + E^((-2 + Sqrt[2]) t)}

Looks a bit nicer in a picture: enter image description here

No error message
