We don't count shinies found in glitches, people. We don't count them for this very reason: it's impossible to verify their legitimacy and the designers didn't intend for them to be there. It's the same as DSRyan and his brother's shiny Mew in the Cerulean Cave. As a glitch (or a lie), it doesn't count. We can't even count classic Celebi Glitch Celebies.
