How to use isAlways to compare two symbolic equations ?

Dear forum members,
I would like to check wether or not two symbolic equations are the same, but I am not able to do this using isAlways function.
syms a b
f1 = y == abs(x);
f2 = y == sqrt(x^2);
isAlways(f1 == f2)
Warning: Unable to prove '(y == abs(x)) == (y == (x^2)^(1/2))'.
> In symengine
In sym/isAlways (line 42)
ans =
logical
0
Why do I get these warnings and this (false) answer "logical 0" ? What am I doing wrong ?
Thank you for your help.
