No, the shell will return the value from the grep appropriately. I
haven't tested this with ash (the shell used by Bering). Only with ksh, 
so I may be wrong. Following commands prove my statement:

$ ps axc | grep xntpd
$ echo $?
1
$ ps axc | grep getty
  494 tty1     S      0:00 getty
  495 tty2     S      0:00 getty
  [...]
$ echo $?
0
