Though, your definition for "||-A" uses two _not_ defined bar-types:
":|||" and "]||:"
You'll get warnings if you try to use "||-A" in a StaffGroup and a
SpanBar isn't printed.

To avoid this, define all newly introduced BarLines as well.

\version "2.18.0"

\defineBarLine "|||" #'("|||" "|||" "|||")
\defineBarLine ":|||" #'(":|||" "|||" " |||")
\defineBarLine "]||:" #'(":|||" "]||:" " ||")
\defineBarLine "||-A" #'(":|||" "]||:" "||")

A = \bar "||-A"

m =
  \new Staff {
    \A a'4 a' a' a' \A
    \break
    a'4 a' a' a' \A
  }

\new StaffGroup
  <<
    \m
    \m
  >>

Please refer to the NR about the already predefined bar-types or use
the following code in a .ly-file to display them in Terminal:

#(use-modules (ice-9 pretty-print))
#(pretty-print (map car (@@ (lily) bar-glyph-alist)))

or the complete list with all settings:

#(use-modules (ice-9 pretty-print))
#(pretty-print (@@ (lily) bar-glyph-alist))
