Because Kaneki/Sasaki is a copycat. He (either subconciously or conciously) mimicks other people's habits and moves.

Like his mother's habit of touching her chin when she's hiding something,

Rize's habits (in the anime http://centipedekun.tumblr.com/post/97830395903/kamishiro-rize-vs-kaneki-ken)

Yamori's finger-cracking,

Touka's pre-fight stretching,

Shachi's moves,

Tsukiyama's blade and

Arima's tactics (distract opponent with a frontal attack then impale them with a surprise attack from underground).

Here's a full list http://mm-whatcha-seidou.tumblr.com/post/115754304975/list-of-things-kaneki-copied-from-others
