You confuse frames and windows. Please have a look at

Those two _windows_ display the same _buffers_.

Sure, cause both windows are associated with the same buffer.

You have to switch to another buffer in one of the windows. You do that
with `C-x b' (`switch-buffer'). There are many different modes and
functions for fast and convenient buffer switching/maneuvering like
`ibuffer' and `ido', just to name a few. Have a look at the docs and
www.emacswiki.org.
