That's an intended behavior. Or at least a side effect of failover
design. If we allow unlimited switching between the master and the
secondary, pgpool could repeat switching forever if we have unliable
network or hardware.
However it would be easy to modify pgpool to allow automatic switch
back (with a risk of unwanted repeating switching, of course). Is
this what you want?
