Given 3 instructions in the body of a stencil apply:

1
2
3

The current unrolling strategy copies the three instructions as a block, as follows:

1
2
3
1
2
3

Interleaved unrolling on the other hand would be:

1
1
2
2
3
3

There are possibly both. positive and negative, performance impacts that come with this change, so we should implement it and measure.
