The following is sheer speculation, not a spoiler. But some of you seem to want to avoid theory, so in that case don't read any further.

If Dr. Ford can make a duplicate of Arnold, then he can make a duplicate of anyone.
Including himself.
So we don't know that he really died in episode 10. He could have made a host in his image and then programmed it to give a speech and stand there waiting to be shot, thus faking his death.
Suicide seems too cheap and it seems out of character for someone willing to go to such lengths (like murder) to protect his plan. I think he wants to oversee/control/help the final narrative.
On the other hand, if Ford is going to massacre the board then why bother faking your death at all? Kill off the board members, replace them with doppleganger hosts, and the park continues with Ford in complete control.
