Is that new? I've definitely made multiple accounts and I only have one number.
A phone number is not strictly required. They use it for some verifications, like suspicious activity. You can switch the number to whichever account needs it at the time, but only one login can have that phone number.
I don't know if it is new, but it is in the help files when I tried to figure out why it required both confirming an email and the phone.
It's fairly new I think. I ran into it first time a week or two ago when going into a test account I haven't used for a while.
Shame really, having at least two users is very useful when building bots. Testing user-specific interactions and such.
