I assume you did add ./testdir to your path...

octave:4> file_in_loadpath ("testx.m", "all")
ans =

{
 [1,1] = ./testx.m
 [2,1] = ./testdir/testx.m
}

octave:5> file_in_loadpath ("testx.m", "all"){1}
ans = ./testx.m
octave:6> demo testx
testx example 1:
 testx("Ha-ha test2")

testx: Ha-ha test2
octave:7> type testx
testx is the user-defined function defined from: /home/dima/octave/testx.m

function testx(str)
       disp(["testx: ", str])
endfunction

%!demo
%! testx("test1")
