Why don't you need two separate app specific passwords for imap and smtp?

Why don't you need two separate app specific passwords for imap and smtp?

Hi,

I have noticed that one can use same application specific password for both imap and smtp. I think this goes against the principle of having app specific passwords and might be anti-security feature. Why is that so?
