Jerry,

Not to worry, it will work fine either way.
History lesson -- during the KAT2 Field Test we found a few units (not all) 
that had the BNC jacks a bit taller than they are now, and they interfered 
when the boards were mated.  The immediate solution was to use 2 lockwashers 
in addition to the standoffs to space the boards a bit further apart.  I am 
going to assume that the diagram was created to show those 2 lockwashers in 
place and has not yet been changed.  The height of the BNC connectors is no 
longer a problem and one lockwasher and one spacer provides sufficient 
clearance (it might even be OK with no lockwasher (only the spacer) between 
the boards).

BTW, yes my KAT2 was one of those with the problem, so I remember it well - 
I shaved some of the material off the BNC jacks to make things fit, and 
later the 2 lockwasher solution was created.

73,
