Now what the heck does that mean?


After this one, the next will occur in 8 years time, the one after that
will occur 105.5 years later, the next 8 years later, the next 121.5 yrs
later, the next 8 yrs later, the next 105.5 yrs later..... you get the
picture?


To expand on this, the reason for the 1000 year comment may be that the
transits do not always occur in pairs. Very occasionally there is just one
almost central transit, while normally there are a pair, one of which
crosses the northern side of the Sun's disk and one the southern side.
IIRC, the next time this will happen is some time in the early "3000"s,
hence this comment in the quote above.
