these states cannot be merged ,until and unless if both the states on different i/p moves to the different states
example:
*{q0,q3,q4}-------->{q0,q1,q4} on i/p 0; and {q0,q3,q4}-------->{q0,q4} on i/p 1;
*{q0,q1,q2,q4}-------->{q0,q1,q4} on i/p 0; and {q0,q1,q2,q4}-------->{q0,q4} on i/p 1;
if this occurs then we can merge ..... but this situation doesn't occur in this question ...
