They are not dodging each other, they just happened to be in different races.
I mean they are not a highly in demand marquee matchup like Coe and Ovett or Tirunesh or Genzebe Dibaba in a race with Defar.
they are 2 young runners, but they have not done anything special at the Professional level, they would have been a marquee matchup at the high School level in the USA, They have no marquee value in Belgium or at the Professional level yet, they do have potential and hopefully will be top runners someday.
