whence defect?

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

   /bin $ path
   Current path:
   .
   /aWorking/Zsh/System
   /aWorking/Bin
   /usr/local/bin
   /usr/sbin
   /usr/bin
   /sbin
   /bin

   /bin $ whence -aS zsh
   ./zsh
   /usr/local/bin/zsh -> /aWorking/Bin/zsh5.3
   /usr/bin/zsh -> /aWorking/Bin/zsh5.3
   /bin/zsh -> /aWorking/Bin/zsh5.3

   /bin $

Can that be right? I'd probably prefer that the duplicate find of 
/bin/zsh was detected (current directory and '/bin' explicitly) and 
removed or perhaps noted, but if it is to show up twice why would the 
'dot' version not show that it's a link as the explicit entry does?
