differences between -false and comma "," operator

The code in findutils is different for -false and comma "," operator.

But the use appears to be same for my tests.

The man page says:

   expr1 , expr2
          List;  both  expr1  and expr2 are always evaluated.
          The value of expr1 is discarded; the value  of  the
          list is the value of expr2.

This appears to be same as:

expr1 -false -o expr2

What is different for the results of -false test and comma "," operator?

Any other use or examples of using comma "," operator that is different from "-false -o"

Also, do you know of any other implementations of find(1) that provide the "," comma operator?

Please carbon-copy me on replies.
