Difference in properties of water as ligand vs 'in lattice'

I'm trying to understand the difference in properties between water in crystals in different positions in the lattice. [In this wikipedia article](https://en.wikipedia.org/wiki/Water_of_crystallization#Nomenclature) It quotes: 



> 
> Both notations can be combined as for example in copper(II) sulfate: $\ce{[Cu(H\_2O)\_4]SO\_4 · H\_2O}$
> 
>

referring to water which is coordinately bonded to the copper and water which is in the crystal structure left over.


Firstly, is this the same as:
$\ce{CuSO\_4 · 5H\_2O}$ ?


And secondly, would there be a difference in how the water acted upon heating? Would it only be the one water in the lattice structure that left or all 5 waters?
i.e. 


$$\ce{[Cu(H\_2O)\_4]SO\_4 · H\_2O ->[heat] [Cu(H\_2O)\_4]SO\_4 + H\_2O}$$


or


$$\ce{[Cu(H\_2O)\_4]SO\_4 · H\_2O ->[heat] CuSO\_4 + 5H\_2O}$$
