Osmosis : --read-pbf, --tee then --merge

Hello ! I want to read a big pbf file (europe.osm.pbf) only one time and filter tags twice on it, so i'm using --tee 2

time osmosis \
    --read-pbf europe.pbf \
    --log-progress \
    --tee 2 \
    \
          --tag-filter accept-relations route=bus \
          --used-way \
          --tf reject-relations \
          --used-node \
          --tag-filter reject-ways building=yes \
                                   public_transport=platform \
                                   highway=construction \
    outPipe.0="bus_route" \
    \
          --tag-filter reject-relations \
          --tag-filter accept-ways highway=motorway,motorway_link \
          --tag-filter reject-ways disused=yes \
                                   highway=construction \
          --used-node \
    outPipe.0="freeways" \
  --merge inPipe.0="bus_route" inPipe.1="freeways"  --write-pbf bus_route_and_freeways.pbf

but this does not work : no error, but osmosis is running forever.
