2nd beat on jump stop: a foot lands earlier than the other

[ysong]

when excecuting a jump stop to end a dribble, the dribbler is supposed to land 2 feet simultaneously on beat 2.

But what if they land with not huge but discernible difference in time? do you call it a violation in the a non-advantageous case:
the dribbler does not gain more ground by pushing the first landed foot, so no obious adavatage is taken, even when he is attacking the basket?

Thanks.
