create tied hash with 1 element  $hash{'foo'} = 'bar' 

Accessing the element increases access count: 
foo => bar:1
foo => bar:2
foo => bar:3
foo => bar:4
foo => bar:5

Create new %hash1 here and reset counter: 
foo => bar:1
foo => bar:2
foo => bar:3
foo => bar:4

Accessing  %hash again shows last count for %hash1 
Global counter is only reset on new tie / object creation
foo => bar:5

Note that this counter is common for all hash elements: 

next => :6
