This information is definitely not correct.
It may work for one account on certain Macs / under certain circumstances, but it's not possible at all on others.
I can easily reproduce this here with my business MS365 Account: on my 2014 Intel iMac it works with one account (only the most current OneDrive app version directly from MS, not the version from Mac App Store), on my M1 MBP it doesn't work at all, no matter which software version is used.
Sorry, but this is the standard mistake people frequently make when judging about bugs, like: "it works on my device, so it should work on all other devices" - this conclusion is just not logical (that's not how software works) and turns out to be wrong in most cases.
