Michael,  I am sorry for being so dumb apparently, but I still don't see it.  
Can you tell me the sequence of steps to reproduce the problem?  

address@hidden ~]$ cat Makefile
all: foo bar bar1

bar1: bar
        touch $@

bar: foo
foo : baz
        touch foo bar
address@hidden ~]$ touch foo bar bar1
address@hidden ~]$ touch baz
address@hidden ~]$ make
touch foo bar
touch bar1
