They say that those old galaxies orbit the
milky way, that 'in orbit around us' makes me
wonder for an explanation. If they just meant
'visible around us' that would be different?


They are part of the Virgo supercluster either way. The Small Magellanic Cloud is in orbit with the Milky Way, at least until we collide with Andromeda. The Large Magellanic Cloud is likely outbound, not bound to the Milky Way, having "recently" passed through it.

.... and note that this lists the Large Magellanic Cloud as being bound.
