Can NPCs ‘scare’ DexNav Pokemon away, and does this ruin a chain

pokemon-omega-ruby-alpha-sapphire

In Alpha sapphire, I'm chaining on Route 101 for a shiny Zorua.

I find one, but the NPC walks over the patch and the Pokemon disappears, giving me the message that it ran away.

Does this kill my chain?

According to Bulbapedia:

A chain is broken when the player leaves the area (including entering a building), encounters a wild Pokémon that isn't hidden, or moves too quickly and scares away a hidden Pokémon.

Hidden Pokémon can be encountered for a chain either with or without the Search function. Getting the message "The Pokémon couldn't be found. Try looking in a different area!" when using the Search function does not break the chain.

So I'm pretty sure that if someone scares the pokemon it will break your chain.
