Yes, you're basically correct. "Behalf" means speaking or acting for someone. There is a slight difference in the meaning of the word "behalf" when used with "in" or when used with "on". "In behalf" is usually used when the meaning is in the interest of someone else or for someone else's benefit. "On behalf" is used when speaking for someone, which is how it is being used in this clip. Ex: On behalf of my entire family, I would like to thank you for all your hard work. Ex: Unfortunately, my manager cannot be here today so I am pleased to accept this award on his behalf. Ex: She wasn't able to attend, so I signed the letter in her behalf.
