That's basically what the "\" is doing. The alias expansion is done at
about the same level as other special character expansions. The "\", by
quoting one of the characters in the alias, "hides" the "cp" from the
alias-expansion code, in much the same way as "\" in front of "*" hides
the asterisk from the globbing code.

So c\p file1 file2 would work just as well.
