Most computer keyboards transmit to the computer a key down and key up
for each key. This is true for modifiers as well (shift, control, etc).
The computer decides if you've held the key down long enough to repeat
and also determines how fast to repeat the key. Which means if the
keyboard buffer is cleared AFTER you've pressed the key the program
won't see the key down and therefore won't consider a key as repeating.
In normal use when the buffer is never cleared typing fast and key
repeat would be equivalent.
