It is surprising!

Unified English Braille which has replaced the older English Braille American Edition uses a lot of "contractions" ('ea', 'be', etc.), shortform words which are combinations of braille (like the braille for 'ab' which can mean 'about'), and wordsigns ('k' for 'knowledge', etc.) in the Grade II forms.

Grade I Braille is closer to what you thinking of.

It's kind of like when you first start studying American Sign Language and realize that a lot of the grammatical structure comes from French Sign Language.
