Multiple users in a single EL Expression

I need to add multiple users to an EL Expression and have tried the following which does not seem to validate (Value: false)

#{securityContext.userName=='john.doe@none.com' && securityContext.userName=='Jack.Doe@none.com' && securityContext.userName =='Jane.Doe@none.com' && securityContext.userName =='Jill.Doe@none.com'}
