the key phrase is "pattern of movement" not "repetition".
you have never squated down to pick anything up?
you have never done any physical labor?
how do you go to the toilet?
how do you jump?
all with racks and pullys i guess........
get what i mean?
in the real world our bodys use stabilizers joints etc to complete a movement or task.....we dont have racks pullys wires etc to complete the stabalizing for us.
i hope i have made my self clear now.
okay for part two.
a person starts with

all guess work)
machine 40lbs
freeweight 30lbs.
s/he works only on a machine and gets the exercise up to 60lbs.
according to you the person will be able to lift around 50lbs on the free weight exercise.
WRONG.
if the person trys the free weight at that weight....feelings will be hurt and so will necks arms and what ever the barbell hits on its way down.
with the bench press for example. if the stabalizers arent strong the bar will not be able to be pushed in a straight line without drifting. have you ever had a bar drift? once it starts it never stops.
BUT.....the person will be able to lift more on the freeweight exercise......but not a great deal more. (significantly less than if they focused on free weight)
yes you can build strength on a machine......but what crossover does it have?
