You should always try to colocate as much as possible when working with a
distributed system. If you colocate properly and set collocated=true, you
will get correct result with the best possible performance. If you can't
colocate, you have to set the flag to false. Result will still correct, but
it will work slower. In other words, this is just an optional performance

Not colocating and setting flag to true is a misuse as this combination
leads to incorrect result.
