In template design pattern, should the extended class implements interface or the parent class?

I just watched the video "Template design pattern" of "Design Patterns in PHP" series. But I'm confused by the source code in Github repository "laracasts/GitHub-Authentication-With-Laravel" -

I see abstract class Provider doesn't explicitly implements "Provider" interface, however the extended class "Github" implements "ProviderInterface". I don't understand why abstract class Provider doesn't... did I miss something here?
