Sorry, I too am a little confused. Trying to understand exactly what is occuring with the second group. But regardless, the test for affordability will be if the employee cost exceeds 9.5% of the income used to calculate. The additional compensation provided by the employer will increase the income used for calculation.
By way of an example, the coverage gross cost is $500 per month/$6000 per year, the employee comp is $30,000. Employee writes a check for $500 per month/$6000 per year and the employer increase the comp by $500 per month, to a total of $36,000 per year. If this is what you are describing? If so the test would be if the $500 per month/$6000 per year paid is 9.5% or below. At $36,000 per year the 9.5% threshold would be $3,420.
