Tied note

[warburtonj]

The music shown at the link below (Beethoven Emperor Concerto) says to hold the tied G note in the right hand (marked in blue) but then the same note is to be played as a semi quaver in the left hand.  How is this possible?

Yes it is played again by the LH.
This is a theoretical marking. Ideally, Beethoven would want that RH G to be tied - because it is another 'voice' - but knows it is impossible. The RH G in the following measure is still Not to be played though.

What themeandvariation said. Ideally you'll keep holding the G to its full value after restriking it with the left hand.
