BZZZZT!  Wrong!

But you came close :-)

Station keeping in these orbits is much more important than in regular
freefall orbits, because the domain of stability is not very large.

For a good story about this, read about the (truly amazing!) recovery
of the SOHO solar observatory, which is located in such a point.
