proper spacing will allow some movement without buckling. these clip systems generally are screwed into to the deck frame across each joist and fit tightly into a cavity running down the side of the boards. hollow decking products will leave open ends that aren't attractive and can collect dirt, leaves, etc. most hollow.
in addition, deck foundations must be connected to the structure to prevent lateral movement caused by high winds, earthquakes, and frost heave. in most regions of the country, that means securing support posts to the foundation with code-approved metal connectors, or having the ends of posts set on concrete deck blocks.
