In list view, Scid does not recognize transpositions in games. In tree 
view it may do.
If you create a small database with only these two games, the tree works 
exactly as you expect. I am not sure, but you may be able to save the 
tree as a single new game. This game should show two variations: One 
after 2.Nf3 and one after 10... Nbd7

I have two manual workaround suggestions (I hope you do not need to do 
this for many games!):

1. (may work)
* Open game 2 and go to the position after 10.... Nbd7
* Strip moves from the beginning (make it start at move 11.Nb3 from a 
FEN start position)
* save this game as a (temporary) new game.
* Merge this stripped copy of game 2, into game 1. This may work, but I 
did not test this myself.
* Delete the temporary copy.

2. (certainly works, but takes some time)
* Open game 1 and go to the position after 10....Nbd7
* Enter the moves as they were played in game 2, starting with 11.Nb3
* save the game as a new game using the data from game 2.
* Reopen game 1 and merge the patched copy of game 2
* Delete the temporary copy.

Depending on how you want the merge result stored, exact operations can 
be simplified a bit (but I guess you got that point).

Cheers,
Joost.
