leave_mm() and lazy TLB mode

There are several places where some comments say leave_mm() disables
TLB flush on CPUs in lazy TLB mode.

My question may be silly, ...

leave_mm() change the value of CR3 register. In my understanding, that
causes TLB flush. Does this contradict with the definition of lazy TLB
mode?
