It actually is the safest and fastest way to break once you got the
technique right. You just don't want to lock the front break but its
actually quite difficult to do on hard ground (when it gets slippery
the technique changes).
Using the front break doesn't make the bike go around the front wheel
since like I said it takes VERY good breaks and even then you need
quite a bit of force to do it (unlike the rear wheel).
Pushing the front break send your weight into the front wheel thereby
improving traction, so if your are not prepared its like breaking hard
with a car, you body goes forward and the bike stays in place. Using
the rear break takes your weight OFF the rear wheel which cause you to
lose traction and skid.
