So I tested it thouroughly and found that its because of the time hubspot APIs take to update the record as mentioned by @tjoyce and I am not sure if support would be able to help much here for this one usecase so I have handled it by checking at my end and only letting the user move forward when API sends the updated response. That way user sees the page only when {{request_contact}} object has the updated data.
Appreciate the help!! Thanks, you both.
