According to what I understand:

These programs will not slow down your Amiga.  They install a routine into
the privileged instruction exception vector.  This routine will check if
the trapped instruction was the illegal 'MOVE SR,<ea>' and will actually
execute the legal 'MOVE CCR,<ea>'.

In other words, these programs will do nothing but sit in memory unless
a program on your Amiga attempts to execute this privileged instruction.
