They only say "immediately".  I don't know if the internal Q clock is runing
during MCLR, so it might have to wait for the next Q0 phase, maybe two to
get the pipline going.  For the 16F87x (DS3029C) the pertinent paragraph is
in section 12.8 on page 124: "If MCLR is kept low long enough, the time-outs
will expire.  Bringing MCLR high will begin execution immediately.  This is
useful for testing purposes or to synchronize more than one PIC 16F87x
device operating in parallel."
