Why in some exercises, where we have to prepare a cash flow statement under the indirect method, depreciation is added in the cash flow from operation only, while in other exercises depreciation is also added in the cash flow from investing (to compute the change in long lived assets)?

I'll provide an example:

In the Monahan case we just sum the depreciation expense of $2,550 in the CFFO and the accumulated depreciation of $600 is used in the change in long lived assets in the CFFI (shouldn't we also account for the $2,550?).

In this other case instead, the depreciation expense of $16M is accounted in both the CFO and the CFI. WHY?
