Julia's assignment behavior differs from Fortran?

I think I understand what is going on under the hood based on this discussion. Can someone confirm that my comments are accurate?

x=[2]  # x points to memory location m1
y=x    # y points to memory location m1
x=[3]  # x points to memory location m2, y still points to m1
z=x    # z points to memory location m2
x[1]=4 # m2 changes value in place, affecting all variables that point there

julia> println(x,y,z)
[4][2][4]
