Is this really true?

And if so, is it an accidental result based on the search engine (i.e. the
search engine picks what it considers to be strong moves, hence, the positions
arrived at correspond to moves selected by the engine)? A self fulfilling
prophesy type of argument.

Or is it an intentional result (i.e. the search engine avoids positions that are
unclear and hence, only picks positions that are reasonably clear to the
program)? I can imagine this for the opening since the programmer can steer the
opening book clear of positions which the program plays badly on, but does it
really apply to the middlegame and endgame positions? I would think that there
is a major difference between understood positions and calculatable positions.

It would seem that the programs are not sophisticated enough to "try to reach
positions that it knows how to play well" with the exception of opening moves.
