What is the downside of using wildcard keychain-access-group

<key>Entitlements</key>
<dict>
  <key>application-identifier</key>
  <string>A1B2C3D4E5.com.example.myapp</string>
  <key>aps-environment</key>
  <string>production</string>
  <key>get-task-allow</key>
  </false>
  <key>keychain-access-groups</key>
  <array>
    <string>A1B2C3D4E5.*</string>
  </array>
</dict>

Would using a wildcard keychain in two shared Apps from the same publisher mean that each app can access every keychain item of the other?

ie. if A1B2C3D4E5.com.example.myapp and A1B2C3D4E5.com.example.myOtherApp had the keychain groups as defined above, then would each of them be able to access ALL of the keychain items of the other? even the ones stored under the group "A1B2C3D4E5.com.example.myapp" or "A1B2C3D4E5.com.example.myOtherApp"?
