Just to clear my question again:
- It wasn't about the comment but concept behind Master/Slave terminology.
- Why are we referring src and dest as Master and Slave. As there is
nothing like that.
- As pointed by Russell and me earlier: Probably it is for choosing
the victim for
reduction of width, in case src and dest addresses are misaligned to each other.

If what i understood is correct, then we should get rid of this
routine or this master/slave
terminology, as this is causing confusion.
