About Sample interleaved mode

Can we have subsampled components in sample interleaved mode ?

If yes then let us assume

Comp 1 with data A11 A12 A13 A14
A21 A22 A23 A24
A31 A32 A33 A34
A41 A42 A43 A44

Comp 2 with data B11 B12
B21 B22
B31 B32
B41 B42

Comp 3 with data C11 C12 C13 C14
C21 C22 C23 C24

then, image samples would be like

(A11 , B11 , C11) (A12 , C12) (A13 , B12 , C13) (A14 , C14)

(A21 , B21) (A22) (A23 , B22) (A24)

(A31 , B31 , C21) (A32 , C32) (A33 , B32 , C23) (A34 , C24)

(A41 , B41) (A42) (A43 , B42) (A44)

Have I done that in right way ???

And how often subsampling is used in sample interleaved mode ??

Is there any criteria behind choosing between line interleaved mode and
sample interleaved mode when we know that components data are
subsampled ?????

Thanks in anticipation
