Fixed in Liferay Connector to SAML 2.0 v5.0.0 for DXP 7.2.

Steps to reproduce:

1. Configure IdP and SP
2. Setup attributes on IdP and attribute mappings on SP
3. Sign in from SP and then sign out
4. Navigate to IdP and change user attributes on IdP (first and last name)
5. Sign in from SP 

Expected result:
Expected user name to be changed on SP

Actual result:
User name remains the same.
