Multiple signatures is needed if only for anybody whose main language isn't English. There are so many companies who internationally use English as their main and only language so would like to communicate with those with a correct signature.
Then if you want to communicate in your main language you need another signature which you need to change.
I also like to send emails on behave on my SO and myself for which I always add that the email comes from us both even though I sent it
