You are absolutely right.  An interesting observation.  However, the
definition of the space character itself, which immediately precedes
the definition of no-break space in 8859-1, shows that the authors of
the standard had in mind space-like behavior; compare this with the
above:

   6.3.1 SPACE (SP)

   This character may be interpreted as a graphic character, a
   control character or as both.  As a graphic character it has the
   visual representation consisting of the absence of a graphic
   symbol.

So "the absence of a graphic symbol" means a blank spot on the page,
not the suppression of escapement.
