Yes, this is the documented behaviour.

OK.

Sortof.  The nobase_ option replicates the hierarchy in your source
tree, which IMO is pretty useless but that's what it does.

You need a directory variable for each directory you wish to install
files into.  See the Automake manual for details, start with §3.3 The
Uniform Naming Scheme[1].

Something like this (untested):

  foosubdir = $(pkgincludedir)/subdir
  
  pkginclude_HEADERS = path/to/header1.h
  foosub_HEADERS = path/to/header2.h
