USM user entry will be overridden while adding v3 user for traps

[heisenberg-7]

I noticed that pysnmpUsmSecretEntry is stored/fetched on basis on security name which can be same for two different devices with same user but only difference being engine-id, so if we add two users (say user 1 and user 2) with user having same username and security name but different engine-id and credentials for auth protocol and priv protocol, only last added user's entry (say user 2) will be available in pysnmpUsmSecretEntry so will that cause any issue in processing of traps from user 1?
