The require merely implies that R2 should be "managed" before R1, and
"managed" being setting the desired state (absent, present...etc) so the
actual value of ensure is unimportant here.
If you want to change your requirements based on the value of ensure you
could do something like....
if $ensure == 'present' {
Resource['one'] -> Resource['two']
elsif $ensure == 'absent'
Resource['two'] -> Resource['one']
}
