Indeed. Even though I checked this page I overlooked this setting. 
Anyway, I haven't checked the source code, but the 
description "Certificate and Key Bundle _Attachments_" suggests that 
this setting only applies to certificates and keys _attached_ to an 
email message.

With S/MIME the certificates are usually included in an S/MIME-signed 
message. With OpenPGP attaching the key doesn't make much sense due to 
the different nature of the PKI (different way of certificate/key 
verification, different way of key distribution, etc.).
