No.
The ZSU being directly attacked, sees an A-10 unmask from "somewhere" in
the forward sector, strafe and/or bomb, then break away and dive back
into terrain cover - all, hopefully, too fast for that vehicle to deal
with by detecting, slewing the turret onto, locking on the Gun Dish
radar, getting a fire control solution, finishing the fine aiming and
firing before the gun vehicle has been damaged, destroyed, or forced to
evade violently enough to break the process.
However, the ZSUs to either flank see the same thing... but are already
covering in that direction (standard principles - mutual support, and
enfilade fire from a defilade position) and are seeing slower angular
rates, so are more able to deliver effective fire - especially because
they're not being attacked themselves at that point. They're also able
to track the A-10 through its run and keep firing even after its weapons
have been released and hit.
There's a *reason* that - to the horror of the Military Reform Movement
- the primary US air-launched antitank weapon became the Maverick
missile rather than the 30mm cannon shell.

Can *you* pass a clear, comprehensive fire-direction order against an
air target, from a closed-down moving vehicle, by VHF voice radio, in
less than ten seconds?
Of course, if there's any radar cover, then the ZSUs will be using that
for alerting, so the A-10 will pop up to find it's *immediately* got a
Gun Dish locking onto it followed by four 23mm cannon demonstrating
their effectiveness. The Soviets were quite good at networked air defence.
Slow and low over the Central Front sounded much better in theory than
it ever looked in practice.
