The \global is necessary because otherwise the assignment won’t have any effect
because
the output routine (and this is where \everyaftershipout is used) forms a group
but this won’t
fix the problem with \page[none].

You don’t need the \chapter commands because it is a \page problem as can be
seen in the following example
(the fix above solves the problem only for page 2 and upwards).
\starttext
\page[yes,blank,yes]
\dorecurse{6}{\input knuth\par}
\stoptext
To really fix the problem you have reset the \pageornamentstate value at
the end of the “yes”, „right” etc. keywords, e.g. (page-brk.mkiv)
\installpagebreakmethod \v!yes
{\ifconditional\c_page_breaks_enabled
\page_otr_flush_all_floats
\page_otr_command_next_page
\ifinsidecolumns % this will move to MUL
\page_otr_eject_page % otherwise sometimes no change
\fi
- \fi}
+ \fi
+ \global\pageornamentstate\zerocount}
and the automatic reset with \everyaftershipout has to be removed, otherwise
things like following example have page numbers on the page 2 and 3 which
should be empty.
\starttext
\page[yes,blank,+3]
\dorecurse{6}{\input knuth\par}
\stoptext
