No, you are not. As the man-page clearly states, this sets the
size of the underlying device as multiple of 512B sectors.

As item 2.17 of the FAQ states, LUKS does not have any issue
with 4k sectors, as it does not split or re-arrange requests.

I would strongly advise to read the documentation before
trying to set up a LUKS volume. There are a number of less 
obvious pitfalls.
