Does not make sense.

No.
When adding like monomials you factor out the variable part that makes the like monomials -like.
In this way, the coefficients are added, the exponent is preserved.
If you change the exponents, the sum will not be a like monomial.
Example:
$3x^{2}+2x^{2} $is not $5x^{4}$.
(Adding squares of x results in squares of x, not other powers.)
$3x^{2}+2x^{2}=$ factor out $x^{2}$ = $(3+2)x^{2}=5x^{2}$
