Doubt before playing halo mcc on pc

If on starting halo mcc on pc “steam” will not conflict if played through the xbox account?

There are a couple of things that go over how Steam will work:

> Q. Seeing that a Xbox Live account will be required, will progress / multiplayer progression carry over from console to PC (ie: Halo Reach multiplayer ranks and unlocked armors)?
>
>
> > A. Within MCC, yes, your progress and progression will carry-over between the console and PC versions. All stats, achievements, Forged maps, and game variants will be shared between all of the games within MCC. Mid mission saves will be unique to each platform and cannot be shared.
> > Your Halo: Reach unlocks and progression from the original game on Xbox 360 will NOT carry over to MCC.
> > And as a reminder, MCC on Steam will require a free Microsoft Account, but not Xbox Live Gold.

In addition there’s a useful graphic here.

You may need to elaborate as I’m not quite sure what you mean by conflict.

A conflict I mean.
An example: my brother plays the halo mcc in the xbox and I in steam. When you see that both are in the same microsoft account one has the obligation to disconnect so that the other can play

Or is it that we can play on different platforms without one disconnecting so that the other can play?
