This is very important point to think about when we try to visualize what's going on between frequency domain and spacial domain. It doesn't seem intuitive at first, but if you think about how a square wave is consist of many frequencies of sinusoids and how a frequency is defined to be a pattern across a direct of the whole image all start to make sense.
