It keeps track for you so you don't need to, but you need to know
how many lines will fit in the current frame.

Let's say the first frame is 3 in wide and holds 8 lines of text,
but the second is 2 in wide.

At each paragraph, knowing how many lines can fit in the remainder
of the first frame, you set a parshape.  If three lines can fit,

\parshape 4 0pt 3in 0pt 3in 0pt 3in 0pt 2in

(The final width applies to all following lines)

You can keep track of the lines-so-far by examining
\prevgraf between paragraphs.

This is all supposition though.  I had the impression 
that flowfram already set the parshape for you, but didn't
really check ever.
