From another thread, in 'Sudoku variants', note that:
There are three levels of coupling in samurai:
none: the five individual puzzles can each be solved without reference to one another;
weak: at least one puzzle can be solved only by sharing solved clues with a neighbouring puzzle;
strong: at least one puzzle can be solved only by sharing pencil marks with a neighbouring puzzle.
The puzzle in question appears to have strong coupling: one puzzle can remove candidates from another.
