In that case, man procmailrc(5) is lying here:
The assignments and substitutions of these environment variables
are handled exactly like in sh(1) (that includes all possible
quotes and escapes),
because sh expands the backticks in an assignment eagerly. (Easily
verified e.g. by running top(1) in one terminal while doing foo=`ls -lRa
/ | tail -1` in another one.)
