This is correct behavior as per manual. If you want it to print A 
then write something like

bar: a_ := $a       # not sure a := $a will work
bar:; @echo $(a_)

 
In contrast the patch fixes the following case:

a := A

%bar : a_ := $a

%bar :; @echo $(a_) 

a := B

foobar:

Which prints (without patch) B.
