I'll give you an example of what these temporary checks mean.

On flights from Athens to Paris:

• you will undergo ID checks before boarding. These are undertaken by a private security company agents. They seem to be quite aggressive in terms of checks, so you can't wave your passage through if there's anything wrong with your paperwork. They will prevent you from boarding if they're not happy with the ID you provide. But if your paperwork is OK you shouldn't have any issues. If there is anything even vaguely borderline about your situation, get to your boarding area early to avoid any issue.

• you will undergo another ID check when you exit the plane. These are undertaken by the french PAF (Police aux frontières). In some situations, they come with portable terminals that allow them to scan your ID and check databases exactly like they would at a traditional passport control booth. Of course, it'll take a bit of time (there are usually only 2 or 3 agents to check all passengers), so if you're in a hurry, take into account the additional time (or be sure to be seated up front).

But as others have stated, those are just checks (like could actually happen nearly anywhere in the Schengen Area), and have no influence on your visa entry count.

In some other situations, you might be deplaned as a non-Schengen arrival and be sent to the regular immigration checks, though they should somehow be able to make the difference between actual non-Schengen arrivals and Schengen arrivals that are temporarily checked. Make sure you keep your boarding pass or stub just in case.

You have more chances of being faced with these temporary controls when travelling from South or Eastern Europe (especially Greece) towards North or Western Europe. I would be surprised if there were any regular immigration checks going from Brussels to Paris. Random customs checks are a different story though (mostly looking from drugs from the Netherlands).
