HFSC deadline time figure in SIGCOM Paper

Hi,

im looking at figure 2 in the SIGCOM97 paper describing HFSC. link:
http://trash.net/~kaber/hfsc/SIGCOM97.pdf

where in this picture can you see that the video sessions data delay is only 10ms, reading the description it should be visible in (b) but i just dont see it?

arrival packets for video session is the same in (a) and (b)
deadline computation for video is the same in (a) and (b)
and departing times is probably for both sessions, it changed slightly from (a) to (b) but nowhere near 10ms
