If the bill had passed, it would have had to have a waiver process and to avoid a personnel train wreck, the waiver would have been immediately granted.
My wife was deployed to within 30 days of her separation. Not only did she receive no time off, she also covered a 3 person shop by herself for her remaining time in uniform while separating, when she should have had 2 weeks off and at least 1 week of no official duties other than separation admin actions. This was of course in violation of a number of official policies, but even the base inspector general couldn't do much more than say "sucks to be you, sorry". And that was over 4 years ago. The personnel cuts are so gross that any attempt to legislate restrictions to military personnel policies will either result in immediate waivers (as the secdef has been waiving title-10 restrictions for years in order to allow the USAF to perform duties specifically given to the Army) or cause a manpower crisis that would result in a showdown between the executive branch and congress over whether or not the current "war" allows the national command authority to use emergency war powers to override legislation that makes it impossible for the military to effectively carry out the orders of the president.
The personnel managers have already had to re-write and toss out nearly every policy they ever had on operations tempo and recurring deployments due to the decreasing size of our military and high operational requirements. A new law attempting to tie the hands of the personnel managers would do nothing more than force a crisis that pits the president against congress with the military members as pawns stuck in the middle.
