关于 apt rdepends 和 apt-cache rdepends 命令的一些问题？

我运行该命令apt-cache rdepends gnome-session-bin并得到以下输出：

gnome-session-bin
Reverse Depends:
  unity-session
  gnome-shell-extensions
  gnome-session-flashback
  budgie-core
 |software-properties-gtk
  gdm3
  unity-session
  gnome-session-flashback
  unity-session
  unity-session
  unity-control-center
  session-shortcuts
  phosh-core
  phosh
  openbox-gnome-session
  gnome-shell-extensions
  gnome-startup-applications
  gnome-session
  gnome-session

  gnome-session
  budgie-core
  ubuntu-session
  ubuntu-session
 |software-properties-gtk
  nautilus-share
  gnome-startup-applications
  gnome-startup-applications
  gnome-session-common
  gnome-session-common
  gdm3

我在网上了解到，如果一个包名称前面有一个竖线|，则意味着该包是一个替代包。而它下面的所有包（直到下一个包，其名称之前有一个竖线），这些都已经是依赖于它的包，而不是我在命令中指定的包。这是真实的？如果是这样，为什么当我运行不带-cache:的命令时apt rdepends gnome-session-bin，名称前面有竖线的包被标记为推荐？

推荐和提供是两个不同的东西。

还有一个问题。是否可以使apt-cache rdepends gnome-session-bin命令的输出具有 Breaks、Recommends、Depends... 标志和版本，就像不带-cache:的命令一样apt rdepends gnome-session-bin？
