Why Microsoft's 'we have Windows 10 Mobile for phones' doesn't contradict Pocket PC vision

[Windows Central]

Many Windows phone fans are anticipating Windows 10 on ARM with CShell on a pocketable device. But how does Microsoft's Corporate Vice President in the Operating Systems Group Joe Belfiore's statement, "we have Windows 10 Mobile for the phone experience", fit into this scenario?
In July, Belfiore stated:

The Windows 10 on ARM effort is about enabling the PC experience on devices that are built on ARM so that they're connected all the time and have great battery life. So the experience is a desktop PC experience, it's not a phone-like experience. For phone-like experiences on ARM, we have Windows 10 Mobile. What Windows 10 on ARM is, is a desktop-like experience so that you get the battery life that ARM processors tend to have.
​

Belfiore makes several points:

• Microsoft has Windows 10 Mobile for phone experiences.
• Window 10 on ARM is for desktop experiences.
• WOA is for always-connected PC experiences and great battery life.

Some people believe Belfiore's statements preclude the possibility of a modular version of Windows that will run on all form factors, including a pocketable telephony-enabled device. So how do we reconcile Belfiore's "we have Windows 10 Mobile for the phone experience", with the expectation of a modular form of Windows on a potential telephony-enabled pocket PC?
