Yes. Well, at least people make assumptions based on the Social Security Death Index (SSDI). that are incorrect.
The SSDI has a field called: Last Place of Residence. Dr. Richard C. Philbrick is shown on the SSDI as having the Last Place of Residence of Mercer Island, Washington,("United States Social Security Death Index," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:JT7Z-ZYD : accessed 29 December 2015), Richard C Philbrick, 18 May 2000; citing U.S. Social Security Administration, Death Master File, database (Alexandria, Virginia: National Technical Information Service, ongoing).) The Washington Digital Archives used the SSDI, so it also shows "Last Contact Location" as Mercer Island. (Notice the change in wording for this field.) But I KNOW that he died in Japan. What's up?
If you don't know that the "Last Place of Residence" field is the last zip code of residence or zip code where the death benefit was sent, you may assume that Dick died in Mercer Island. But, the death benefit is sent after death to the person who is managing the estate. In other words, it is sent to the address of the estate administrator or executor. So, a person who died in one place may have a totally different location as "Last Place of Residence."
Use as many sources as you can. In this case, FindAGrave does not give any place of death. The only confirmation of the place of death as Hagi, Japan, was his obituary.
