Yes, that would be it.

Is the explanation in this reference what you hoped you had correctly
recalled?:

2.3.4.3 Rules for coding IEASYMxx
Follow these rules when coding IEASYMxx:
1. Define new system symbols that are 1- through 8 characters long,
excluding the required ampersand and the optional period. For example, you
can define a system symbol called &PAGESYM3, which contains an 8-
character name, using the following SYMDEF statement:
SYMDEF(&PAGESYM3='LOCAL3')
2. Do not define resolved substitution texts that are longer than system
symbol names (including the required ampersand and excluding the optional
period).
</quote>
If so this removes concern over the substitution text expanding the space
occupied by the symbol text.
