strange output of regex


Hi all...

Code:
[vinay@TEG test]$ echo grapes>"text sample2"
[vinay@TEG test]$ cat "`ls text*le2`"
grapes
[vinay@TEG test]$ cat "`ls text*2`"
cat: text2
text sample2: No such file or directory
Here I feel 3rd command should display contents of file "text sample2"...The output is really looking strange...How is this working ?

I got the concept.....
shell is giving the cat command a single parameter text2..
