If you were talking about a work issue which ended well & then as you were leaving your manager's office, he stops you on your way
and asks you whether they'd see you on Monday. (Knowing well that he knows that I'm around & regularly checking my schedule).
This has happened before, seems like he's looking to keep talking as opposed to real urgency of discussion. My relationship with my manager seems more like equals rather than understudy & supervisor. I sometimes wonder if it's my place to ask him if things are ok - as we're both married,etc.
