Gambler Fallacy Paradox

The following does not seem to square with the gamblers fallacy bias.

Lets take a roulette wheel (50-50 red black only, ignoring green)

True
>4 R in a row is less likely than 3 R in a row

So given that it is less likely, and there are only two options, why isnt it more likely to be black on the fourth spin?
