this is related to tex's way of breaking pages; when settings change 
while tex has not yet broken a page, they get lost

  bla bla (not enough for a page)

  \setupheadertexts[x]

  bla bla 

versus:

  bla bla (not enough for a page)

  \page \setupheadertexts[x]

  bla bla

i try as good as i can to handle this but esp in border cases a user has 
to force a break before such settings that affect the 'current' of 
'next' page; it's just a matter of where/when (settings are expanded. 
not delayed)

here the problem is in:

    \installpagebreakhandler{last}{}    

if you change this to issue a (one) page break, it will probably work ok
