That Expert players are better at recreate real games than ‘fake’ positions is one of the things Adriaan de Groot (https://en.wikipedia.org/wiki/Adriaan_de_Groot) noticed in his studies with expert chess players. (“Thought and choice in chess“ is worth reading if you’re interested in how chess players think. He anonymized his subjects, but Euwe apparently was on of them)

Another thing he noticed is that, when asked to set up a game they were shown earlier, the errors expert players made often were insignificant. For example, they would set up the pawn structure on the king side incorrectly if the game’s action was on the other side of the board, move a bishop by a square in such a way didn’t make a difference for the game, or even add an piece that wasn’t active on the board.

Beginners would make different errors, some of them hugely affecting the position on the board.
