Incorrect directory in Appian IIS Documentation?

Hi, all! I would like to ask if it is my misunderstanding, or there is a problem in the following link:

https://docs.appian.com/suite/help/18.2/Configuring_IIS_with_JBoss.html

for point 6 it said,

Create a text file with the name isapi_redirect.properties under the <ISAPI_HOME>\ISAPI folder using the following example settings:

 extension_uri=/Redirector/isapi_redirect.dll 
 log_file=<APPIAN_HOME>\Redirector\log\isapi_redirect.log 
 log_level=info 
 worker_file= <APPIAN_HOME>\Redirector\conf\workers.properties 
 worker_mount_file= <APPIAN_HOME>\Redirector\conf\uriworkermap.properties 
 strip_session=1

However, according to the definitions section and point 8-13, which said:

<ISAPI_HOME> refers to the Jakarta ISAPI Redirector installation directory.

• The default <ISAPI_HOME> location is C:\Redirector.

the properties file should be created under the default c:\Redirector folder's subdirectories.

If that so, why do line 2,4,5 in the coding shown above point to the directory inside <Appian_Home>?

In other words, the "Redirector" folder should not be ever created in <Appian_Home>, isn't it?
