Here's the information I received:
Making Contributions with After-Tax Dollars
Currently, annual contributions by employees are limited to $18,000 (or $24,000 for those age 50 years or older) on either a pre-tax or Roth basis. Effective July 1, 2015, employees may contribute an additional $29,000 per year with after-tax dollars increasing the total contribution opportunity to $47,000 each year ($53,000 if you are age 50 or older).
Streamlined Deferrals
To help make it easier for you to take advantage of this after-tax enhancement, we are implementing a streamlined deferral election. Streamlined deferrals eliminate the need for you to make separate contribution elections. Beginning July 1, once you reach the 401(k) IRS maximum of $18,000 ($24,000 if eligible), your contributions will continue as after-tax contributions, up to a maximum employee contribution of $47,000 ($53,000 if eligible).
Opportunity for Tax-Free Investment Gains with a Roth 401(k)
In addition, you will have the opportunity to convert your after-tax contributions to Roth 401(k) contributions. By converting after-tax contributions to a Roth 401(k), if certain conditions are met, any investment gains earned after conversion may be withdrawn in retirement tax-free!

Am I the only one who noticed this? It sounds like he wouldn't need to do inservice withdrawals, the employer will convert it to Roth 401k. Wonder what the details are.

I don't read it the same way. I believe the employees has to take the action to convert it. That's the way it works with my plan with the Mega backdoor Roth conversion. I had to take the action, and can convert once a quarter. But...what did catch my eye was the 'if certain conditions are met' statement. The OP better make sure to check with HR and maybe their plan administrator to see what those conditions are.
