Sorry for the late response, we were out to dinner lol.
Now:
That's just not how it works. Just because at some point the human member may step in and press a button for a part of it, the bot would have done most of the reservation. If someone writes a book or builds a building and then someone else comes in and puts their name on it in the end, who "wrote" or "built" it? The first person, not the second. Otherwise it would cause a ton of problems in weird situations where as long as a member did part of something, they could let someone do the rest. Or as long as a member got part of a benefit, they could let someone else have the rest of the benefit too. Makes my head hurt.
And you don't even have to take my word for it, the online booking terms and conditions are pretty clear. They break it down by each step, accessing, searching, booking, modifying, etc.
From this document:

"Terms & Conditions Disney Vacation Club® On-Line Booking For Disney Vacation Club Resorts And Disney Dining Plan Terms and ConditionsEffective November 1, 2018
Disney Vacation Club Members with a valid Club ID login and PIN # are authorized to access this "On-line Booking" module.
This allows you, if you are a Disney Vacation Club Member in good standing, to
(1) search for available Disney Vacation Club accommodations;
(2) to make a reservation at a Disney Vacation Club Resort using your vacation points (including banked vacation points and/or borrowed vacation points, if applicable);
(3) modify a previously booked vacation points reservation at a Disney Vacation Club Resort
(4) cancel a previously booked vacation points reservation at a Disney Vacation Club Resort
(5) order, pay and modify a Disney Dining Plan option for your stay at a Disney Vacation Club Resort; and
(6) make waitlist requests for accommodations that are not currently available. "We", "Us" or "Our" refers collectively to Disney Vacation Development, Inc. ("DVD") and Disney Vacation Club Management, LLC ("DVCM"), and "Disney" refers collectively to Us and the Walt Disney Family of Companies."
So, only a member is authorized to access the booking module at all.
Only a member is allowed to even search for accommodations.
Only a member is allowed to make a reservation
Only a member is allowed to modify a reservation
Only a member is allowed to cancel a reservation.
Etc.
The "first step" you mention would include at the very least accessing the booking module and searching the accommodations, both of which are ONLY authorized activities for members. A computer program cannot be a member, a member is the person with their name on the deed.
