Possible Feedback Function Limitations

My intention is to have multiple non-related transfer functions then perform a unity feedback operation on them, all at once. My Code is as follows:

K=[1:2]';
pone=ones(1,length(K));
G=tf(mat2cell(K*conv([1 3],[1 5]),pone),conv([1 -2],[1 -4]));
T=feedback(G,pone);

I can't figure out why I'm not getting the right feedback output. For this case I get:

G =

From input to output...
     s^2 + 8 s + 15
 1:  --------------
     s^2 - 6 s + 8

       2 s^2 + 16 s + 30
   2:  -----------------
         s^2 - 6 s + 8

Continuous-time transfer function.

T =

From input to output...
     0.25 s^2 + 2 s + 3.75
 1:  ---------------------
      s^2 + 4.5 s + 13.25

       0.5 s^2 + 4 s + 7.5
   2:  -------------------
       s^2 + 4.5 s + 13.25

Continuous-time transfer function.

What feedback value are you expecting ?

Thanks for the quick response! I am expecting:

T =
From input to output...
   s^2 + 8 s + 15
1:  ---------------------
    2s^2 + 2 s + 23
     2 s^2 + 16 s + 30
 2:  -------------------
     3 s^2 + 10 s + 38
Continuous-time transfer function.

Basically G/1+G; *sorry for the typo
