Why we should not change content of returned value from TextView#getText()?

Android Docs in about TextView.getText() say:

Note: The content of the return value should not be modified. If you want a modifiable one, you should make your own copy first.

Also TextView has setText (CharSequence text, TextView.BufferType type) method and you can pass TextView.BufferType.EDITABLE to it to enable casting result of getText() method to an Editable. As Docs say the purpose of Editable interface is:

This is the interface for text whose content and markup can be changed [...]

My question is: If we can pass Editable to the TextView and get it, why we should not modify it?
