I hope I correctly understood what you did. You just opened two files
in emacs without closing the first of them explicitly.

Emacs does not automatically close buffers (i.e. files in your case)
when you open a different buffer (or file) but keeps those buffers
open but invisible. So you do not need to reopen the first file. You
simply can switch to this file by either using the "Buffers" menu or
by typing C-x b and supplying the name of the buffer you want to
switch to. If you type the TAB key instead you get a buffer which
shows all currently open buffers. 

Read the chapter "Using Multiple Buffers" in the emacs manual for more
information.

BTW. The C-x b command supporst a history of the last visited buffers
which seems to be what you want.
