gpio numbering inconsistent??

Drogon writes on his site

gpio -g …
The optional -g flag causes pin numbers to be interpreted as native BCM-GPIO pin numbers rather than wiringPi pin numbers.

This would imply that omitting -g would using wiringPi numbers. Yet, when I do

gpio export 5 out

then

ls /sys/class/gpio

shows that

/sys/class/gpio/gpio5

exists but not

/sys/class/gpio/gpio24

which would be the correct BCM number according to https://projects.drogon.net/raspberry-pi/wiringpi/pins/.

I'm probably missing something obvious here- but what??

the man page has this to say:

   export Export a GPIO pin in the /sys/class/gpio directory. Use like the mode com‐
          mand above however only in and out are supported at this time.  Note  that
          the pin number is the BCM_GPIO number and not the wiringPi number.
