I was thinking slightly longer term than the initial colonisation event
or
even the first decade or so, but once the colony is fully established
and
has interstellar trade going on (maybe that's just my view of the
GZGverse)
then I'd expect to see some backflow, though it may not be on the scales
seen around Earth (though even here some migrations are one way - my
Granddad came out and never got enough cash together to go back even for
a
visit).

Cheers
