y from the same row as max x sqlite documentation

while reading the sqlite change log I came across this statement

2012-03-20 (3.7.11)
...
Queries of the form: "SELECT max(x), y FROM table" returns the value of y on the same row that contains the maximum x value.
...

I found the commits that implement this feature, in the hope of finding documentation but no luck.

I find myself using this feature all the time and wondering:

• Is there documentation of this feature?


• When can I rely on it applying?


• Are there gotchas in using it?


• Are there similar queries that it doesn't work for?
