New Sweden PTO and Leave policy

There has been a lot of errors in accounting for paid time off in Sweden, and
making it try to match our US policy. We now realize that the best thing to do
is to have a more standard vacation policy in Sweden that conforms with the
local expectations.

The new, local policy is a traditional accruing time off policy, with a base of
25 days per year.
I'm not sure what is meant by “A more favourable practice at an individual company shall be retained” here.
