In HSRP only the primary router can respond to the "virtual" MAC address.
The secondary router responds to it's bia.
Secondly, by law of switching only one MAC address (unique) can exist in a
VLAN at a time. The switch will remove the
original entry if the same MAC address appears on another port in the same
VLAN.
By default, in the event the primary router fails the secondary router must
wait 9 seconds (3xHello of 3 seconds)
before he declares himself active. This is why there is always an
interruption in HSRP.

You've all been hoodwinked. The "problem" description
is nothing more than HSRP with the optional MAC
address set on both parties, to the same address. In
this case all traffic goes to both routers, which is
what you want so that in the event the primary fails,
the secondary can pick up all the ongoing flows
without a hitch. No ARPing needed, and no frame loss.
