no. Either

A) Permanent gaps, the samurai's head could get pulled to bits again by anyone

or

B) they stick permantly only when back with what they were orrginally joined to.

As evidanced by Sanji swapping bits of the Samurai after he got put back together.

Either way, his head is not permanantly stuck with the legs
