I think he was refering to the Jupiter sized planet located at about the
same distance from the star as our Jupiter. . .do keep up. . .

from the site:
Berkeley - With the help of improved measurement techniques, planet
hunters at the University of California, Berkeley, have been able to
detect a Jupiter-sized planet orbiting a nearby star at a distance
comparable to Jupiter in our own solar system.

However, on the same page, the third and second to last paragraphs do say:
,----[ <URL:http://exoplanets.org/esp/47uma/47uma_announce.html> ]
| The two-planet system bears an intriguing resemblance to our own. The new
| measurements by Fischer and her colleagues peg the mass of the inner
| planet at 2.5 times that of Jupiter, at least, while the newly discovered
| outer planet has a mass at least 3/4 that of Jupiter, yielding a mass
| ratio of 3.3. The mass ratio of Jupiter to Saturn is also 3.3.

| The average distance from the star to the inner planet is 2.09 times the
| average distance of the Earth from the Sun, a unit of measure called an
| astronomical unit or AU. The outer planet is 3.73 AU from the central
| star. For comparison, Jupiter and Saturn are at distances of 5.203 and
| 9.555 AU, respectively.

That means that there's a planet in the system that's over twice the mass of
Jupiter and which is only around 2AU from it's star. It strikes me that
while everything written above does suggest an "intriguing resemblance" in
regards to relative masses the resemblance isn't terribly good in terms of
distances from the star.
