Naming of methods in RSA_METHOD

I implemented some custom engines and RSA_meth_set_priv_enc seems to map 
to other libraries' RSA decrypt operation (NCryptDecrypt ||||on Windows 
CNG, Cipher class with Cipher.DECRYPT_MODE on Android). They can do a 
TLS connection just fine with a self-signed cert.

I looked at another custom engine and they seem to also use RSA decrypt for

BoringSSL's (deprecated) rsa_meth_st only has a sign and a decrypt, 
having no encrypt operation:

Is this just a naming quirk? I want to put down the nagging feeling I 
have a bug somewhere.
