Well, no. That hilighted part is actually wrong, as the report itself makes clear.

The standard for Volume I (page 16 and 17 of the PDF):
In reaching the charging decisions described in Volume 1 of the report, the Office determined whether the conduct it found amounted to a violation of federal criminal law chargeable under the Principles of Federal Prosecution. See Justice Manual § 9-27.000 et seq. (2018). The standard set forth in the Justice Manual is whether the conduct constitutes a crime; if so, whether admissible evidence would probably be sufficient to obtain and sustain a conviction; and whether prosecution would serve a substantial federal interest that could not be adequately served by prosecution elsewhere or through non-criminal alternatives. See Justice Manual § 9-27.220.
The standard for Volume II (page 213 of the PDF):
We first describe the considerations that guided our obstruction-of-justice investigation, and then provide an overview of this Volume:
First, a traditional prosecution or declination decision entails a binary determination to initiate or decline a prosecution, but we determined not to make a traditional prosecutorial judgment.
There's more detail there, of course, but it's quite clear that the standards used in Volume I and Volume II are not the same, and the standards outlined for Volume II specifically and explicitly apply only to Volume II
