EMA is a moving average calculation where the weight is exponentially weighted. In general, they are both equal. However there is some flexibility in the definition, that the "weight" is defined in other way even though using exponentially weighting. If no context is available, they are the same. Otherwise, I would read through what the author really meant.

I agree with Christopher Imanto. These two terms are used interchangeably in practice.

The exponential smoothing method gives greater weight to the more new observations, while moving average give equal weight to all observations
