Not to dwell too much on what you have written, just note that your regex matches:
one alphabetic character, one or more alphanumeric characters, one or more 'X' characters
So, the '$' and '%' are not being matched at all. It is the 'XXX' string that is being matched (following the '$' and/or '%'). 'XXX' satisfies the pattern.

logcheck-test(1) General Commands Manual logcheck-test(1)NAME
logcheck-test - test new logcheck rules easily
SYNOPSIS
logcheck-test [-q|-i] [-a|-s|-l FILE] [-e] [-P PREFIX] [-S SUFFIX] RULE
logcheck-test [-q|-i] [-a|-s|-l FILE] -r RULEFILE
DESCRIPTION
logcheck-test parses a log file for matching lines specified by a single rule or a rule file. If using a single RULE you can set a PREFIX
and a SUFFIX to write new rules easily.
OPTIONS -h, --help
Show usage information
-a, --auth.log
Parse /var/log/auth.log for matching lines
-s, --syslog
Parse /var/log/syslog for matching lines
-l, --log-file FILE
Parse FILE for matching lines
-i, --invert-match
Show line that don't match the RULE or the RULEFILE
-q, --quiet
Suppress rule summary at the end of output
-e, --surround-rule
Surround RULE with standard prefix and suffix:
^[[:alpha:]]{3} [ :[:digit:]]{11} [._[:alnum:]-]+ RULE$
-P, --append-prefix PREFIX
Append PREFIX to rule prefix. Option can be given multiple times
-S, --prepend-suffix SUFFIX
Prepend SUFFIX to rule suffix. Option can be given multiple times
-r, --rule-file RULEFILE
Use file RULEFILE for rule input
EXAMPLES
With logcheck-test you can easily write and test new rules.
Test a single rule against /var/log/syslog:
logcheck-test -s "RULE"
Test a single rule against ~/log, surround the rule with standard prefix and suffix and append "kernel " to prefix:
logcheck-test -l ~/log -e -P "kernel " "RULE"
Test the rules in rulefiles/linux/ignore.d.server/kernel against ~/log:
logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel
Test which lines the rules in rulefiles/linux/ignore.d.server/kernel doesn't match:
logcheck-test -l ~/log -r rulefiles/linux/ignore.d.server/kernel -i
EXIT STATUS
On successful matching logcheck-test will complete with exit code 0. An exit code of 1 indicates no successful matching.
An exit code greater then 1 indicates an error occurred. Textual errors are written to the standard error stream.
