[Avodah] basic parsha question from Toldos -- Ulai

[Sholom Simon via Avodah]

Shavua tov,

Much ado is made of the world "Ulai" that the servant {Eliezer] used 
(at 24:5) when he said "perhaps the woman" will not want to come back 
-- as though he wished that possibility would happen.  As opposed to 
if he had used the word "pen".

But in Toldos (29:12) Yaakov says the same thing: "Ulai" my father 
will discover me.  I looked at a Mikraos Gedolos and didn't really 
see anything on that word (not that I'm very fluent).  Surely 
somebody must talk about the similarity in language, no?

(My own thought is that perhaps Yaakov (Mr. Emes) was so 
uncomfortable that he had subconscious thoughts that we wanted to get caught).

Thoughts anyone?
