> IIUC the labels have to match a line in the file uniquely, which the DW_TAGs wouldn't

CHECK-LABEL doesn't have to match a line in the file uniquely. What happens is that all the -LABEL directives are processed first, in order, subdividing the input text into regions. Then the non-LABEL directives are processed within their respective regions.

So you could have

  CHECK-LABEL: DW_TAG
  CHECK: DW_AT_name ("foo")
  CHECK-LABEL: DW_TAG
  CHECK: DW_AT_location
  CHECK-LABEL: DW_TAG

which would search only the first tag for "foo" and only the second tag for the location attribute.
