Because they MULTIPLEX the rows, so a row is only on for a fraction of a second.

Seconded.
"turn on one column"
now turn on the leds on that column you want turned on...The other leds will not be affected because their columns are turned off.
"turn off that column"
"Turn on the next column"
repeat.....
