Is it possible to catch 2 of the same legendary beasts in pokemon silver? - make pokemon happy silver

I am surprised to find another way roaming Pokémon Entei money too!
Heres the story:
Johto I walked from one end to find the animals, I found my first Entei, north of the town of Cherry Grove, then my second just below the dark cave, but I would not find in the same time, I stopped after the first Open my gameboy, did the same, from the city of new crust is created and homelessness, and came to the dark cave that was!

I'm really confused, what one of you has 2 from the same animal?
