Ah. In that case, you want:

if header :matches "Subject" "\\*xyz\\**"

I tested this and it works; see
<https://datatracker.ietf.org/doc/html/rfc5228#section-2.7.1>:

  "?" and "*" may be escaped as "\\?" and "\\*" in strings to
  match against themselves.  The first backslash escapes the second
  backslash; together, they escape the "*".  This is awkward, but it is
  commonplace in several programming languages that use globs and
  regular expressions.
