Perhaps I should add details in case something else is wrong.

There are 3 contexts that are used when ordering:
and the default case "installed".

If you dig through the bit fields, adding context markers like
"(post)" narrow the context of the dependencies so that
	installing <=> erasing
contexts do not overlap.

The dependencies in the "installed" case, i.e. plain old
with no context marker, are part of the dependencies
used for both installation and erasure ordering.

So adding
narrowing the scope, cannot possibly solve the problem
as you have stated. With or without the "(post)" context
marker, install ordering will use the dependency for ordering.

All that adding "(post)" does is exclude the dependency from
being used for erasure ordering. But that's a whole different
