It seems not simply a matter of operator precedence since [7] evaluates to neither [3] nor [6].

In[1]:= Series[a + (b1 + b2) x, {x, 0, 1}];
% // Normal;
% /. {b2 -> 0} 

Out[3]:= a+b1 x

In[4]:= Series[a + (b1 + b2) x, {x, 0, 1}];
% /. {b2 -> 0};
% // Normal

Out[6]:= a+b1 x

In[7]:= Series[a + (b1 + b2) x, {x, 0, 1}] // Normal /. {b2 -> 0}

Out[7]:= a + (b1+b2) x
