Mearls confirmed you cannot concentrate on a spell and psionic discipline at the same time. One concentration slot.

If the designers wanted to allow this stacking, they could have used a different term than concentration

This.

As for your question: I don't believe thinking in terms of "slots" is helpful: a character can concentrate on one thing at a time, period.

Yeah, just think of it as a type of Action. A special continuous action. And note that whenever you cast a new spell/discipline that requires concentration, the old one automatically drops.

 

[Leatherhead]

Actually, I just realized that this is totally clear and everyone is just not remembering the entire concentration rules:

any effect that causes a mystic to lose concentration causes the discipline to end

The following factors can break concentration:

• Casting another spell that requires concentration.

So yeah. The this kind of thing is right out.

Nothing else to add, other than I'm hoping Jeremy Crawford's "Rules as Fun" term keeps spreading. It's a great shorthand way for legitimizing house rules as just as valid to a home table as book text or "voice from on high."
