Then it seems that the program you call "find" is not strictly following the 
POSIX
standard and your command line depends on unspecified behavior of a specific
find implementation.

It seems that you did not understand the problem:

find expands "{}" only if an argument is containing only the two characters 
"{}".

echo allows you to check for the behavior of find.
