Why does a Custom tile based on EL Expression works for HCM URL but not for FSCM URL?

Summary:

We have created a Custom tile under My Client Groups using an EL Expression based on #{securityContext.userInRole[ }}.
The tile does NOT appear (as expected) when we use the /hcmUI/faces/FuseWelcome, but the same Tile appears (unexpected) when we use the fscmUI/faces/FuseWelcome

Please advise. Thanks.
