Initially Holy Roman Emperor Maximilian of Austria (Habsburg) had a succession treaty with king Vladislaus II of Bohemia & Hungary (Jagiellon). When his third wife finally gave birth to a daughter (Anna) and a son (Louis), this was revised into a double marriage treaty.
These pacts between the houses of Habsburg and Jagiellon, referred to Hungary (& Croatia) and Bohemia, which only recently had a member of the Jagiellon dynasty on their thrones and previously had Habsburg rulers too. It did not affect Jagiellon Poland-Lithuania.
The marriage treaty was quite clear that Louis (Lajos/Ludvík) would marry Mary, however Anna would be married to a Habsburg archduke (Charles or Ferdinand). Maximilian deliberately wanted to keep some options open, since he preferred a French or English match for Charles V.
According to various inheritance laws Ferdinand was entitled to a part of the inheritance. Charles insisted that the only part of the inheritance, which would have to be divided amongst them were the Austrian Hereditary Lands. Ferdinand initially had wanted to divide a larger part of the inheritance, so include the Spanish and Burgundian inheritance.
After their first inheritance treaty Charles still kept Tirol and Further Austria, however after resistance of the Estates of various parts of the Austrian Hereditary Lands, Charles finally agreed to give Ferdinand the entire Austrian Hereditary Lands.
Once Ferdinand inherited the Austrian Hereditary Lands (1521), it was clear that he was the one, who would marry Anna.
No Charles wanted his son Philip as the successor of his brother Ferdinand as Holy Roman Emperor, since Ferdinand was the elected king of the Romans and thus the successor of the Holy Roman Emperor. However at this point Ferdinand, who had been very loyal to Charles, choose his own family and ambitions over that of his brother Charles. Also the German prince-electors preferred the native Austrian Habsburgs over the 'foreign' Spanish Habsburgs, not to mention that they didn't like the prospect of another absentee monarch.
Charles couldn't make Philip the sole heir of all Habsburg dominions, since the Austrian branch had inherited Hungary and Bohemia and were recognized in their possession of the Austrian Hereditary Lands. However if Philip would have been elected as king of the Romans/Holy Roman Emperor, the branches might have stayed closer together.
Also Charles was not obsessed by Power, he was concerned about the Reformation and the unity within his dynasty and of Western Christianity, as a devout Catholic (as was Ferdinand, their only difference is that Ferdinand was a bit pragmatic politically) he wanted the (Catholic) Church to stay united.
