Steps to reproduce:

https://mytestsite.com/ (contains "test site")

should redirect to

https://myauthpage.com/ (contains "auth page")

1) Steps
Name: Test Site
URL: https://mytestsite.com/
Follow redirects (checked)
Timeout: 15s
Required string: auth page
Required status codes: 200

Result:
failed: required pattern "auth page" was not found on https://mytestsite.com/
return status codes: 200

Expected:
The required pattern "auth page" should be found on https://mytestsite.com/

2) Steps
Name: Test Site
URL: https://mytestsite.com/
Follow redirects (unchecked)
Timeout: 15s
Required string: test site
Required status codes: 302

Result:
failed: required pattern "test site" was not found on https://mytestsite.com/
return status codes: 302

Expected:
The required pattern "test site" should be found on https://mytestsite.com/

Conclusion: Follow redirects is inconsistent with the required string and required status codes
