When prompted for the second word, you can use M-p to insert the 
word you just typed, and then use M-u to upcase it before hitting 
RET for the final time.

In general, input history (with M-p, M-n, M-r, and M-s) is active 
and available in many situations in the minibuffer -- it's always 
worth trying it to see if it's there.  The node "Minibuffer 
History" in the Emacs manual has more details.
