It really depends on whose defintion of a typographic "point" you take. You can read one persons account on the subject at the link:
The history of the American POINT SYSTEM
According to that article, at least, the European standard for a "point" is 0.0148" which is slightly larger than 1/72 of an inch.
However the American Standard is listed as 0.0138" or 1/72.46 which is slightly smaller than the point you mention.
Nevertheless you are correct in your assesment. I was thinking of the 72.27 figure and got the magnitude wrong when dividing.
Perhaps the article would be more accurate to say that "Depending on the source, the definition of a typographic point can be slightly different from 1/72 of an inch but Quartz 2D adopts the PostScript convention which defines it to be exactly 1/72 of an inch". Which is really what's important to know in this context anyway.
