I heard an interview once and they explained that since their motto is:
Learn, Chat and Play With The Pros
The "pros" are required to play a certain amount of time per their contracts. He didn't mention any requirements about the limits they have to play, but it wouldn't surprise me if they were randomly asked to play micros.
Pros I put in quotes, because they sponsor some players that are not professional poker players. Some of these dimwits wouldn't stand a chance against some of the regs around here.
except sp, who crushes all
There are no subliminal messages here.
