Are they any guides which provide this?

A mask would prevent ink from being applied on a certain color run in the offset printing process. Steve Birmingham is the go to guy for this stuff but I think in the case the yellow pass was likely impacted by an inadvertent part of the mask being left in place over the team name that was later corrected in the press run, or in second run, and allowed the team name to be properly inked in yellow once the offending portion of the mask was removed.
