It works fine for us in practice, though you'll find bizarre statements to
the contrary in the JunOS documentation, such as this in 9.1 and earlier:

"The following restrictions apply: On a single routing platform, you cannot
configure the same VRRP group on multiple interfaces"

And this in newer versions:

"On a single routing platform, you can assign a unique VRRP group to only
one interface..."
