VM placement in Fault and Update domain

$

Hi ,

From what I have read, VMs are distributed in FD and UD in round robin fashion.So for example following scenario exists:

FD-3,UD-20 and VMs- 60 

then as per my understanding each FD will have 20 VMs each and each UD will have 3 VMs and since in this case VMs with same UD will be on different FD as well so one UD will be spread across multiple FD's.Is this understanding correct ?

The reason I am asking is that at some places I have read below distribution of VMs:

"The 60 virtual machines would be spread evenly over the 20 update domains, with 3 machines in each. . My update domains cannot be spread evenly (20 / 3) so I should expect 7 update domains to exist in two of the fault domains, which means that a localized outage could impact up to 21 virtual machines at a time"



This assumes that one UD will exist in only one FD which I believe is incorrect .Can someone please confirm this ?
