The redesignated subsection gains a heading
What the document says“Subsection (i) of section 223 of the Communications Act of 1934 (47 U.S.C. 223), as so redesignated by subsection (a), is amended”
Subsection (c) of this section makes what it labels a technical and conforming amendment. The subsection that subsection (a) moved from (h) to (i) gains a heading: the word Definitions, followed by a dash, is inserted before the words For purposes of this section.
What the document actually says“Subsection (i) of section 223 of the Communications Act of 1934 (47 U.S.C. 223), as so redesignated by subsection (a), is amended”
The part that got moved gets a small fix.
A heading is put in front of it. The heading is the word Definitions. The law calls this change technical.
