Actually, they *don't* work exactly like centralized version control.
That's kinda the point; they offer excellent facilities for edit conflict
resolution that makes the facilities provided by CVCSes look positively
primitive by comparison.  DVCSes are specifically designed to facilitate
a certain amount of simultaneous development of the same files with
generally error-free merging when the second of the two changesets gets
added to a given repository.

The idea that multiple people can work on the same stuff at the same time
is kind of central to the necessary capabilities of a DVCS.
