Comment (by m_i_n):

 I've made some tests and I can see it matters if it's a custom post type,
 not regular post.

 This query gives 2 results...

 {{{
 <?php
 $args = array(
         'post_type'      => 'books',
         'posts_per_page' => 2
 );
 $query = new WP_Query($args);
 }}}

 but...

 {{{
 <?php
 $args = array(
         'post_type'      => 'books',
         'posts_per_page' => 2,
         'tax_query'      => array(
                 array(
                         'taxonomy' => 'book-category',
                         'field'    => 'term_id',
                         'terms'    => array(16),
                 )
         )
 );
 $query = new WP_Query($args);
 }}}

 gives all `book-category=16` results like the `posts_per_page` parameter
 would not exist.
