Not necessarily. It just suggests the bottleneck for life lies at whatever point is after mars. Nothing would suggest that complex life gets progressively more difficult to evolve.
Right now there are a few places for the great filter. To my knowledge:
1. Life
2. Multicellular life
3. Intelligent life
4. Interstellar colonization tech
If you make it through all levels you should be colonizing the galaxy and detectable by us therefore.
Finding life with a separate origin than ours removes one of the possible spots for the great filter and makes it significantly more likely that the great filter is ahead of us rather than behind.
This is a question that will help with the survival of humanity.
