I don't understand the last sentence?

On the other hand, redirect.yo explicitly adds a sect() in man page format
only.  The net effect is that the heading "Redirection" is shown as a
chapter heading in html/pdf but as a section heading in man.

That's because zman.yo defines chapter() to expand to nothing.

Yes, the texinode() directives are placed on the chapter(), not on the
sect() with the same name.

The mapping between chapter() nodes and man pages is not one to one;
there are more chapters than man pages.

What end result would we like to achieve?  Once we nail that down we can
think how to implement it.

At least, we could grep for any instances of ifnzman(see the section
`foo'...) where `foo' is a texinode() of a chapter(), and fix them.

Or we could hack at the yodl to reduce the differences between the
various output formats.

There are probably other options
