meaning of 'Depends: R (> 3.0.2)'

In knitr-1.13 the DESCRIPTION file's Depends line uses a ">" instead of the
usual ">=".
  Depends: R (> 3.0.2)
I don't see the strict greater than in Writing R Extensions.  Does it
really mean that 3.0.2 is not suitable and that whatever version comes
after it is?
