AMA: Microsoft Store and Windows app management

Can someone please explain the Blocking Apps feature in ESP where "Only fail selected blocking apps in technician phase" in the most simple way possible? I purposefully created a Win32 app that fails on either detection or exit code, I have used that setting on an app assigned to a group and listed under blocked apps in ESP. Regardless of the setting for "only fail in technician phase" the app that fails always breaks Autopilot during pre-provisioning. What is the specific purpose of the setting? What is the specific test case we can create to test it? https://techcommunity.microsoft.com/t5/intune-customer-success/update-to-windows-autopilot-pre-provisioning-process-for-app/bc-p/3809809
