After Harry left the shelter, Albert, hidden beneath a Disillusionment Charm, quietly returned and used a spell to silently restrain Griphook and Gornuk, who were discussing the matter in Gobbledegook.

Though it did carry a hint of being overly clever, he still preferred trusting his own intelligence and judgment most of the time.
It was a common failing among geniuses.
Although Albert was a fake, even a fake genius was still a genius.
