Umm... not sure if OP is serious.
There are still two signing periods... Feb is still national signing day and that signing period ends in april, like in years past. I think they did it more so early enrollees can get financial aid sooner. Also it binds them to their commitment, so if say a guy wants to confirm his commitment but still take a couple visits he can do that as well, though I'm not sure why any college would waste an OV on them.
Basically it's for early enrollees.
