As LanX says, just to clarify: 
D:\>perl -e "print crypt('foo', 'bar');"
ba4TuD1iozTxw                             # note the hash starts with 
+ba
D:\>perl -e "print crypt('foo', 'ba');"   # same as above
ba4TuD1iozTxw
D:\>perl -e "print crypt('foo', 'b4r');"  # and this one starts with b
+4
b4aMdyw.oyhyI
D:\>perl -e "print crypt('foo', 'b4');"   # and this one starts with b
+4
b4aMdyw.oyhyI

Hence feeding a crypted value as salt into crypt is eqivalent to using the original salt.
