eth0 is not plugged into network. so I can test locally before
switching the wire.

arp request for 192.168.1.2 is responded to by eth1 on machine B. That
seems buggy to me.
Does it still do so if you set either "arp_ignore" or "arp_filter" (I
can never keep those two straight)? Could be the "weak-end-system"
design of the stack at work here. That allows any interface in the
system to respond to an ARP request for any of the IP's assigned to any
of the interfaces.
worse, it continues to do it after unconfiguring
eth0:1 and eth0.
As in simply marking it "down?"
