But that limit is per card. Also, there is no limit that I know of for how many starpoints you can transfer to miles using the Starwood AMEX.
The only limit would be the very high limit imposed by American on the maximum number of partner miles one can accumulate in one year, so I wouldn't worry about the 50,000 limit since it won't apply to the Starwood AMEX.
