I have no idea what you mean with passive dependencies.

There is nothing magic regarding dependencies.
I guess the only thing you need to know is, that there is a flag called
DefaultDependencies=yes|no.
The default is yes, if not specified.
With this property set, units get a default set of orderings and
dependencies.
IIRC they slightly differ depending on the unit type, e.g. service or
socket.
It's comparable to services being started in rc2 and implicitly
depending on rcS.

If you use DefaultDependencies=no, you'll need to specificy you
dependencies explictly.
