It would be helpful to see the original line that you extract with grep, and the original sed.
I can only guess, but it sounds like there might be two instances of one of the words. Consider this line of text:
If the words that you are looking to capture things between are text and pattern, and you use the set of sed replacements shown below, you'll get nothing on the output:
The reason this produces nothing as output is because the first match matches the whole line and deletes it.
If you are certain that word two only appears once on the line, then reversing the sed substitution commands will help, but it's not foolproof.
And, you don't need to cat a file to sed. Sed is capable of reading the file and thus you'll reduce overhead:

vlatai(1L)vlatai(1L)NAME
vlatai - Lojban word analyzer
SYNOPSIS
vlatai [ -v ] [ word ]
DESCRIPTION
vlatai is a program that reads a list of Lojban words from standard input, one word per line. In its usual mode, it writes a single output
line for each input line, advising of which kind of Lojban word the input line is. If the input word has cmavo prefixed onto it, vlatai
shows the individual cmavo and the base word itself.
In the verbose mode (obtained using -v), the workings of the internal state machines used for scanning the word are exposed. This may give
some insight into where an error lies on words that can't be parsed, especially if the output is used in conjuction with the report files
built during the compilation process.
Note that vlatai is primarily a testbench for the word categorizer/splitter inside jbofihe. vlatai is not fully supported or documented as
a stand-alone program.
OPTIONS -v Verbose; show lots of information about the evolution of the internal state
word The word to check. If no 'word' argument is supplied, the program reads words from standard input, one word per line (with no
whitespace around it.)
