why my legs are giving me false sensory appreciation?

since,

you are not thinking of reliable sensory appreciation of the head and neck
which is fundamental to release the whole body.
if you maintain the sequence from head neck to back then the sensory
will be easy for getting by your self.

why iam not able to think of head neck, asis_pubis symphosis length at a time all together

since iam lazy.
i have to think more than one thing at a time , and this is fundamental
concept of alexander technique.
eventhough with out neck and head which is cardinal direction and first direction, the other directions wont progress much and it is a waste of time.

so, i have to do compulsary more than one direction at a given point of time.
