Datum feature symbol attached to a callout common to hole and c'bore/sink 1

[Burunduk]

When a datum feature symbol is attached to a callout common to both the hole+counterbore or a pattern of them as in This example or to a hole+countersink or a pattern of them as in this example, is there any rule in ASME Y14.5 or related standards that tells clearly that the datum feature is understood to be the hole(s) and not the counterbore/sink(s)?
Or maybe it's vise-versa?
Or maybe it should be understood that both features/patterns act as a "common datum feature" (of hole+c'bore/sink, repeated in pattern if applicable)? Are those placements of the datum feature symbol unambiguous? I tried to find something about it in Y14.5 with no success, but maybe I'm missing something?

Both examples are from here.

Burunduk,
Now I think I understand your question! Sorry for being so slow! This one might have been litterally lost in translation.

I meant that there are two ways to dimension the counterbore. 1: with a tolerance of a profile or 2: with a ± dimension plus position tolerance (which is called location tolerance in French).

When positionning the counterbore, I would do it with regards to it's individual hole, just like in figure 10-27 you supplied earlier.

I now understand that I should have paid more attention to my English the first time. It can be misleading.

Supergee,
Thank you for the clarification.

When positionning the counterbore, I would do it with regards to it's individual hole, just like in figure 10-27 you supplied earlier.

Do you mean that you would use the INDIVIDUALLY concept when applying position,but not in the option with profile? Or would both options be applied individually (to always control each counterbore to its corresponding hole only, regardless of whether it's profile or position)?
