No, you're exactly right. Look at the text of Gad's statement:
"I am fortunate to have seen some of the plans Bob Iger has in store for the future and that future couldn't be in better hands."
How would a random actor be privy to the future of The Walt Disney Company? Sure, there will be Frozen lands and new Frozen movies. We knew that already. He's talking about information we don't have. What this indicates is that there was an event where influencers were invited to see some of the upcoming plans. This likely included presentations by Doctor, Feige, Kennedy, and D'Amaro. Something of a private D23. Iger also probably attended and personally met with the influencers.
Iger is running a political campaign. Complete with celebrity endorsements, adds, attacks in the press, etc. Private events with politicians and influencers are standard operating procedure for the political realm. All you need to know about why Disney is operating this like a political campaign is on Disney's executive biography page. Disney's current head of Communications Kristina Schake has the following background:
"Ms. Schake has served at the highest levels of government, as Communications Director for First Lady Michelle Obama and Deputy Communications Director for Secretary Hillary Clinton’s 2016 presidential campaign."
She's literally a political operative. She's using the entire playbook. No conspiracy.
