The tags are stored at the beginning of the file. Since it's not possible to add new data into the beginning or middle of a file, adding tags normally means having to copy all the audio data that comes afterwards. The reason this is sometimes fast is that FLAC adds a padding block with unused space after the tags. As long as your new tags fit in the padding block, nothing has to be copied. If this is a frequent problem for you, look at the documentation for FLAC's --padding option. Setting a larger padding size might help.
