is that correct ?

The intention to live in the UK on a permanent basis is quite important as British Citizenship is only granted to applicants who intend to live in the UK. However, after being naturalized, it is not legally possible to maintain such a requirement, therefore this requirement is in place only whilst an application is pending – once the application is successfully completed, the requirement no longer pertains, and one is no longer constrained to live in the UK.

I am thinking studying a little bit in Germany or France and after I might have a job there (I am not sure yet but I may so....)
Please let me know

You are absolutely totally correct. Once you get your BC, you can go where you want to, for however long you want to.
