Some of this is due to local coronavirus lockdowns and the uncertainty around when they will be lifted, but there is also uncertainty about when schools and day cares will open again. Providing child care will keep a lot of people at home even if they aren't required to be.
On top of that, a lot of people won't want to go back to the office, not because they enjoy working from home, but because they will still be afraid of getting the virus. Being at the office probably won't feel normal anyway due to continued social distancing and the use of masks.
Combine that with concerns that the virus may surge again in the Fall, maybe necessitating another lockdown, and you have a recipe for working at home much longer than what might be legally required.
