Switching to ground....

That doesn't answer my question. If the taxiways are managed by Ground how
can there be a problem with an aircraft switching to Ground once he's on the
taxiway?

As I wrote in my first post: At this particular airport, this particular
taxyway is managed by Tower. This is an exception. This is mentioned in
the AIP, and pilots are expected to read the aiport chart and before
using an airport.

Well, if it isn't, it means an instruction to taxi to a specific point is
not an authorization to taxi to that point.

You got it.

That's not safe.

Yes, it's perfectly safe (as safe as something can be, of course).
Pilots are required to know the rules. Just because rules are different
to those you are used to doesn't mean they are not safe. Nothing strange
about this rule when you are used to it.
