cloning = generating twins

not only would the Ys be the same, but the rest of the genome as
well. Given that cloning would ever be possible at all, or desirable
(discussing that would be far too off topic). The two humans would
only be as similar as two twins, in fact they would be twins. As
twins, they would often differ in their personalities and other
attributes quite a bit. (Neurons, for example, develop connections
randomly, hence variation. Genes are activated/ suppressed by
methylation of the DNA, partially random, partially controlled by
mother's egg and so on and so on.)

In summary, gentically they would be the same.
(With the exception of the very rare normal random mutations in the
first cell or that may occur in a cell during the very early
development, early enough that the cell in which it occurs will
result in a large proportion of cells in the embryo.)

Hope this makes sense.
