At age 62, we can not 'suspend' payments at all. That is not available until we are of full retirement age and that right is not going away. See here regarding voluntary suspensions and the age requirement:
What is going away is the effect of what happens when we do suspend.
The "free loan", so called strategy, was this: When we apply for retirement, 62 or over, at times we soon decide we didn't want to do that and we rather NOT have applied at all. If we are within 12 months of our application, even if we have collected 11 payments, we can request a "withdrawal" of that application. It is a one time per lifetime event option. If we are permitted to withdraw, we return the moneys we took, without paying interest for that time we had the money - ergo the "free loan." This was a much bigger deal prior to about 5 years ago, when there was no 12 month time limit. Back in the day, people would "borrow" the payments for years and years, and then withdraw the application. In theory, they could have 70k in the bank (never spent, just put in an interest bearing account), earn the interest, then withdraw the application, keep the interest earned over those years on that money they didn't spend but just invested/saved, but pay back the principal. The SSA curbed that a few years back, but allowed the cruz of the righ to 'withdraw' an application to remain for 1 year after applying - to ensure it really does still allow for the mistaken decision, but not to encourage 'free loans'. Here is the SSA word on the right to withdraw an application: https://socialsecurity.gov/planners/retire/withdrawal.html
Keep in mind that suspension of benefits, entirely different, is undergoing change in that you can still suspend after your FRA if you go back to work or otherwise decide you don't need them yet, but are under 70 and want to collect "delayed retirement benefits" so your benefit later, after suspending awhile, will grow by 8% per year deferred (up to age 70). The change is that IF you do suspend to grow your own benefits amount, your dependent's benefits on your record (if any) will also be suspended. So the COST of suspending can be very great.
