You are RIGHT!

In C++ this function even is named still as ConvertBitSet()...

Explain me please, why you want to use BitSet ?

As far as I see, in YOUR Task as in many others:

    you have some RecID on left table
    you need find SEVERAL linked records on right.

FindLinked() returns ArraySet() because it is easy assume that number of
childs linked to ONE left record will be not big.
