whats the deal?

The calipers will have metel lines were ever there is not a need for flexable line. You should have a flexable line weither steelbraided or stock rubber on the strut assembly going to the car. This allows the assembly to turn as the steering turns. If you look in the wheel well you should see hard line then flex line where the strut turns then back to hard line into the calipers. If you have nothing but hard lines then it's "to go thru and fix time"...

I hope light has been shed...

It goes hard line at chassis - to rubber/flex line which joins another hard line at the strut housing, this hard line ends at the caliper.

I think what is being asked is why does the flex line terminate into another hard line instead of eliminating that extra connection and just connecting to the caliper. So the brake line routing would be:
Chassis side hard line - to rubber/flex line - to caliper. Basically eliminating the hard line that is attached to the caliper.

To answer, I simply don't know why it is done that way, except to possibly eliminate as much rubber or non solid line as possible for safety.

dont new cars use straight flex from the strut to the caliper? it makes sense..

.....more connections, more trouble...i think they build cars just to frustrate people...its not even about money.. its about getting a laugh as we "do it your self" people go nuts over silly engineering ideas.
