A fine question. Sorting out bridging behavior with IRB gives me a headache.
My two cents:
When you say, bridge 1 bridge ip, you have basically disabled the IP
protocol addresses on all interfaces in bridge-group 1. The only interface
IP addresses that would be active are those outside bridge-group 1 and the
IP address on the BVI interface.
When you say, no bridge 1 bridge ip, you have re-enabled the IP protocol
address on the interfaces in bridge-group 1 (except the BVI interface).
Now, IP is routed across the interfaces within and outside of the bridge
group, and other protocols are bridged.
I do not claim to be an expert here and would love clarification from
someone who understands it fully.

Quick question to everyone,
when IRB is doing both bridging and routing for ip, what takes precedence?
let's say I got
int e0
ip add 1.1.1.1 255.0.0.0
bridge-group 1
int bvi 1
(I'm not specifing IP Address here)
bridge irb
bridge 1 route ip
bridge 1 bridge ip
I noticed that I can't ping 1.1.1.1 from another router, unless I do "no
bridge 1 bridge ip"
