On what basis is the offer letter provisional?

In the annexure section of the offer letter, it is said that this offer letter is provisional and can be cancelled if the eligibility criteria is not met(12th Marks/ Qualifying Examination). Are they just talking about the 12th Marks and PCM aggregate here or are they also talking about January JEE Mains Result? I applied through SNUSAT and have recieved the offer letter but my JEE mains result is yet to be announced, though, i meet the 12th boards eligibility criteria. So, is my Offer letter confirmed now, or subject to being cancelled according to my JEE Mains Result?
