Looks to me like:
B "i'm stealing your $2"
A "you ain't stealing my $2, i'm gonna steal your raise mug"
B "bugger, he sussed me, i need to pretend i have a really strong hand, reraise!!"
A "oh heck, he must actually have a hand but i'm priced in to call this and try to hit"
So they both have a very wide range
