Answer:
That is a great question, and in this case you are right. I believe this is another important reason to pray this way everyday, because it totally confuses satan and his demons while cutting right to the heart of God’s will for our lives.
Romans 8:26-27 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
These verse show two things…that as we pray in the Spirit we make groanings (some audible and some that cannot even be heard) that is the Spirit praying through us. To give satan credit for being able to understand this is giving the devil way too much credit.
Second, there is only one who can search the hearts of man and know the perfect will of God…God Himself here represented as the Holy Spirit. Giving the devil credit for knowing what the Spirit is praying is also then giving him credit to be able to know the hearts of man which he does not. We know God alone knows the hearts of men….Jeremiah 17:10 I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.
Too many people forget the devil is not God’s opposite…God has no equal so therefore He has no opposite. The devil is a created being, an angel that fell from grace. The devil loves it when we give him credit he does not deserve, we should be careful not to.
God Bless,

Ps – one other note…even if the devil knows some of the Heavenly languages he does not know them all. This was a new work God did on the day of Pentecost thousands (if not millions or billions of years) after the devil lost his place in Heaven.
