If the information in the box is true, whose reasoning is correct?

Scrub jays are a species of bird that will bury some of the nuts they collect in order to save some food for later. Scientists studying the species made an interesting discovery:

Some scrub jays move nuts they bury if they see other scrub jays watching them bury the nuts the first time.
It is only those scrub jays who have previously stolen nuts from other scrub jays that move their nuts.

Logan: “That means a scrub jay must be able to predict which other scrub jays will steal its nuts.”

Kimberley: “If a scrub jay moves a nut it has buried, you can be sure it has had its nuts stolen before.”
