That seems more “oh we fucked up and didn’t realize our changes to the law imply this” than “Germany forces men to request permission to leave”.
Highly doubt it. This is a very new addition. Their fuck up was to pretend for ideological reasons that a country doesn't need an army. And that the concept of considering a country home and its culture as something worth preserving is just right wing bs. Now they are surprised that only very few men deliberately registered for armed service ...
It is very likely this was done intentionally. Maybe not all people involved in making this law noticed it, but the person working on article 2 did this intentionally. They explicitly list that this article is always active now:
> (3) Außerhalb des Spannungs- oder Verteidigungsfalls gelten die §§ 3, 8a bis 20b, 25, 32 bis 35, 44 und 45.
