Please become accustomed to supplying decent and sufficient information whereupon an analysis can be started. Like contents of the EXAMPLE variable, the (meaningful) code around that if construct, your OS and shell versions.
None of your conclusions above can be acknowledged nor disproved due to lack of info. The construct you show checks the process environment to see if it contains the string which is the expanded value of EXAMPLE, be it (part of) a variable name or an assignment string.

times
times(1) User Commands times(1)
NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
