Without it, every

dstY[x] = src[0][x] << 6;

would turn into

dstY[x] = ((uint16_t*)(src8[0] + srcStride[0] * srcSliceY))[x] << 6;


So it improves readability and possibly moves some repeated calculations
out of the loop.
Could also just be 3 independent variables srcY/srcU/srcV, if the array
is what looks odd.
