Is it possible to chain roaming legendaries on platinum?

Question

I have seen a video on this and I didn't know if it could work. First, stand in a big area of grass with the roaming legendary in that route. Secondly, use pokeradar and go to the flashing patches. When you find a legendary, kill it and the chain starts and continue the chain. At the chain of 40, keep using the pokeradar until you find a shiny patch. It should be the shiny legendary you chained.
Pls tell me whether this will work. I'm in doubt. XD

Answer 1

No. That has to be a hack, considering that if Azelf/ Cresselia faint, they will only reappear after beating the elite 4 again.

Shiny chaining only works for ordinary Pokemon.

I'm just going to add an to what fondant said. You can only chain the pokemon that can only be found on the specific route
