1) The official doc for which indates that "which -all" displays the paths to all items on the MATLAB path with the requested name, as well as any files in special folders that have been implicitly added to the path.

2) In R2022b, files with name including "sl_customization" (m or p files) can be found with Windows Explorer in MATLAB root folder as shown below. And none of the pathstr are members of MATLAB path as you can find with the script below.

str2test_R2022b = [
    "C:\Program Files\MATLAB\R2022b\examples\slrequirements\main\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\rtw\rtwdemos\crl_demo\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\qualkits\iec\ecoder\tests\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\rtw\rtwdemos\pil_demo\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\toolbox\coder\advisor\examples\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\resources\Sldv\en\ModelAdvisor\sl_customization.xml"
    "C:\Program Files\MATLAB\R2022b\toolbox\rtw\rtwdemos\examplePilF28335\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\examples\ecoder\main\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\examples\slcheck\main\sl_customization.m"
    "C:\Program Files\MATLAB\R2022b\examples\systemcomposer\main\sl_customization.m"];
is_in_path = false(1, length(str2test_R2022b));
for i = 1:length(str2test_R2022b)
    [pathstr, name, ext] = fileparts(str2test_R2022b(i));
    is_in_path(i) = contains(lower(path), lower(pathstr{1}));
end

is_in_path =
  1×10 logical array
   0   0   0   0   0   0   0   0   0   0

3) On the other hand in R2019b, files with name including "sl_customization" (m or p files) can be found with Windows Explorer in MATLAB root folder as shown below. And 23 of them are included in the MATLAB path. This is what is shown in "which -all".

str2test_R2019b = [
