No, it will ignore those and *only* digi the packet when it
is first heard from a visitng mobile that is using WIDE2-2
or WIDE3-3.  It will digipeat it ONCE as WIDE2-2* or
WIDE3-3*, so that at least the mobile gets heard once.

But in the new n-N paradigm, the standard MOBILE path 
should be simply RELAY,WIDE and when you head cross
country on a long interstate you might want to change to
##LNK5-5 for interstate ##.  Remember, a 5-5 on a LNKn-N
system only does 3% of the damage that a WIDE5-5 used
to do...  So it is quite fine with me...
