Because it might contain a Spannable
object. From the doc:
If
setText()
was called with an argument ofBufferType.SPANNABLE
orBufferType.EDITABLE
, you can cast the return value from this method toSpannable
orEditable
, respectively.

return a CharSequence
instead of a String

it actually returns Editable
and not CharSequence
but you can store it in a String variable by calling toString()
on it.
