Yes, and for completeness I'd like to point out that this doesn't just apply to the right-hand side of the equation you gave. The "=" is just syntactic sugar to let you do variable assignment using infix notation:

In[1]:= FullForm[Hold[a={1,2,3}]]

Out[1]//FullForm= Hold[Set[a,List[1,2,3]]]

Worth pointing out, thanks! I see how that works.
