Part 4 tenancy etc etc etc

Am I misreading/misinterpreting this or does this mean that at the end of a 1 yr lease, a tenant can say 'No I am not moving out' if the landlord just wants to move them on as not happy/comfortable with them?

Security of Tenure (Part 4)
Security of tenure is based on 4-year cycles from the date Part 4 of the Act comes into force (i.e. 1st September 2004).
The landlord can terminate without specifying grounds during the first 6 months, but once a tenancy has lasted 6 months, the landlord will be able to terminate that tenancy (known as a “Part 4 tenancy”) during the following 31/2 years only if any of the following apply;

the tenant does not comply with the obligations of the tenancy
the dwelling is no longer suited to the occupants
- accommodation needs (e.g. overcrowded)
- the landlord intends to sell the dwelling in the next 3 months
the landlord requires the dwelling for own or family member occupation
- the landlord intends to refurbish the dwelling
the landlord intends to change the business use of the dwelling.
