The table below presents an aligned extract of verselets in Lv14-06 Both verselets discuss the lepor-sacrifice procedures done with the cedar, hyssop, worm-died-wool and live bird. The alignment justifies the Rashi assertions that There are two takings: The priest a) takes the bird and b) takes the cedar-hyssop-worm-died-wool; but there is one one dipping: The priest dips the entire bird-cedar-hyssop-worm-died-wool package together.

Lv14-06	the living bird: the priest shall take it, with the cedar wood, and the scarlet, and the hyssop,	The underlined verb take in the middle of the sentence separates the objects taken into two distinct groups: (Group #1) The living bird and (Group #2) the cedar, scarlet and the hyssop. This implies that there are essentially two groups taken.
Lv14-06	and the priest shall dip them and the living bird in....	Unlike the previous sentence where the objects of take are separated into two distinct groups, in this sentence, the verb dip applies to the entire group - the living bird and the cedar-hyssop-worm-died-wool. So the priest does one dipping of the entire package of bird-cedar-hyssop-worm-died-wool.

Advanced Rashi: But how do you do two takings and one dipping? Rashi explains further: You tie the cedar-hyssop-worm-died-wool (one bundle) and then take that bundle and the bird (Because of the two bundles there are two takings). You then dip them together.
