Because someone outside Adobe defined a flate compression value and ignored the value defined by Adobe as part of the TIFF standard.

The non-Adobe flate compression value should be read, but never written. Use the Adobe flate compression value when writing.

Thanks for the info, Chris! It's been a while now but I recall that After Effects wouldn't read AdobeDeflate tiff files. I hope that's changed now. :)
