In Pythonese, they performed

SomeBank.extend(BofA)
BofA = SomeBank
del SomeBank

so that id(BofA) is now what id(SomeBank) was, not what was id(the BofA I 
grew up with).  The name was definitely part of of the acquisition value.

OT, but not completely irrelevant to a discussion of names, ids, and 
values.
