The first file is stocking in memory (array P,Q and C in code)
Only lines sample number parent of the second file is stocking in memory (Array V in code) and so, only these lines must be at begin of the second file.
If you launch only the awk commande before pipe, you see it return only lines of second file that represent parents.
EDIT: each children pair in second file must be consecutive.

colcrt
colcrt(1) General Commands Manual colcrt(1)
Name
colcrt - filter nroff output for CRT previewing
Syntax
colcrt [-] [-2] [file...]
Description
The command provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstriking is
destructive. Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output lines.
Options
- Suppresses all underlining. It is especially useful for previewing allboxed tables from
-2 Causes half-lines to be printed, double spacing the output. Normally, a minimal space output format is used which will suppress empty
lines. The program never suppresses two consecutive empty lines, however. The -2 option is useful for sending output to the line
printer when the output contains superscripts and subscripts which would otherwise be invisible.
Examples
A typical use of would be:
tbl exum2.n | nroff -ms | colcrt - | more
Restrictions
Can't back up more than 102 lines.
General overstriking is lost; as a special case `|' overstruck with `-' or underline becomes `+'.
Lines are trimmed to 132 characters.
