I would actually interpret the manual as that "-vf" applies filters in the 
order you specify from first to last and that the "-vop" applies in reverse.

Quote from MPlayer 1.0rc1-4.1.1 manual:

"-vf <filter1[=parameter1:parameter2:...],filter2,...>
Setup a chain of video filters.

-vop <...,filter2[=parameter1:parameter2:...],filter1> (OBSOLETE)
Setup a chain of video filters, to be applied in reverse  order.
Deprecated in favor of -vf."
