There is no such requirement unless you are imposing it by your own design
decisions.

Why do you want to do this? Is this in a model spec? A controller spec?

You _can_ stub (not mock) chains like this:
MyModel.stub_chain(:where, :last).and_return(xxx)
You can also set chained expectations like this (but I wouldn't recommend it):
ar_query = double('ar_query')
ar_query.should_receive(:last).and_return(nil)
MyModel.stub(:where).and_return(ar_query)
