This will make centering the maneuver more difficult (since you can't draw the line out to compensate for getting there early), however, I think it should make the maneuver easier to fit in the box. With a good tail wind inserting three pauses with four unrushed half rolls eats up the box REAL quickly. This allows us to fly two 2/2 rolls on each side of center going all the way to center to complete the 2 of 2.
I'm anxious to give this a try.

Reversal is immediate. Point rolls require hesitation
Immediate reversal means as soon as model's wing reach horizontal,
model needs to start the opposite roll. There are situations in
maneuvers where opposite rolling elements are present (Reverse Point
Roll, Reverse Knife Edge,etc., for example) where reversal MUST NOT
happen immediately because a hesitation must be flown of some duration.
But in TWO, 2/2 Rolls Opposite, the description requires 2 individual
and complete 2/2 rolls to be done, in opposite directions. This follows
established precedent (first done in F3A assymetric rolling maneuvers)
where two different rolls were required in opposite directions. I am
pretty sure F3A folks remember the 1 1/2 Snap. 4/8 Roll opposite they
flew about 6 or 7 years ago. It was the first such maneuver introduced
into Pattern

Look a little further down:
Two of Two Point Rolls Reversed – From level upright or inverted flight,
model performs one-half (1/2) roll to level inverted/upright flight,
hesitates,
performs another one-half (1/2) roll in the same direction to level
upright/inverted
flight. Immediately the model
performs one-half (1/2) roll to level inverted/upright fli
ght in the
opposite
direction to the 1st two half rolls, hesitates, performs
another one-half (1/2) roll in the same direction to level
upright/inverted
flight.

Masters 2009: Two 2/2 reversed
I checked the RCA and I didn't see anything for Two
(2) , 2/2 Reversed. I used the NSRCA link to the RCA
2009-2010 RCA-32: "
Two
(2), Two of Four (2/4pt) Point Rolls Reversed: From inverted flight.
Model rolls
through 180 degrees, hesitating at each 90 degree point. Then rolls
through
180 degrees in the opposite direction hesitating at each 90 degree
point. At
each hesitation wings are parallel or vertical to the horizon. Center
is
middle of upright flight. Downgrades:
1. One-quarter rolls more or less than
90 degrees
2. Model does not
hesitate after each one-quarter roll
3. Roll rate not constant
4. Changes in altitude
5. Changes in heading
Two
point (2/2pt) roll – slow roll reversed: Model performs a two point
(2/2pt) roll, immediately
performs a slow roll in the opposite direction. See descriptions
of
two point
roll and slow roll for requirements and downgrades for all elements
except
centering. Roll rates need not be the same for the two point (2/2pt)
and the
slow roll. Downgrades:
1. Centering. The center of the maneuver
is determined as the middle of combined roll elements. Center is
determined
by the midpoint between the start of the two point (2/2pt) roll and
finish of
the slow roll.
2. Roll reversal not immediate.
