Ok here is my thought process about this- the committee always only meets on Fridays. The last batch of decisions went out April 28th and those students have 2 weeks to decide. 2 weeks post April 28th falls into the week of May 12th, which is the week of May 15th- meaning the committee is meeting on the earliest Friday they can after they have finalized numbers of open seats after this last batch of decisions went out. I think the "if" is just terms they have to use to not give false hope or promise that students are going to then freak out about and use against them.
