I would assume one is for early phase registration (101domains - May 1-7), and one is general registration (gandi - May 8). If the domain isn't registered in the early phase, you'll be in line to have it registered on May 8.
I was confused because gandi and 101domains did not explicitly state the phase. And gandi took my money and deducted it from my account but apparently did not actually obtain the domain yet.
