No it is isn't. See the ticket for an explanation:

It does suggest we may want to consider reseting Maxima's counter for
dummy variables before calling solve. RJF, how does one do that in
Maxima?

equations from the results of an earlier solve, then Maxima should
ensure that newly generated variables do not intersect with the
variables already occurring. Maxima currently does this by assuming
that users won't use variables of the form z1,z2,... by themselves and
by ensuring that it generates a monotone series. If you violate the
first assumption you can already get nonsensical responses:
