Clearly to cater for people that still have 0845/0870 inclusive bundles.

Prior to this they were offering 0844 access numbers, after switching from 0845/0870.

Bear in mind if your thinking of using 0845/0870 access numbers  that some suppliers EG BT may charge you normally if  they find you using inclusive 0845/0870 calls to make intl calls.
