Yes. Move the condition down.

<form action="" method="post" name="form1">
  <input type="submit" name="submit">
</form>
<?php if (isset($_POST['submit'])) { ?>
<form action="" method="post" name="form2">
  <input type="submit" name="submit">
</form>
<?php } ?>

But note that, you have the same name in both the form's submit button, so it is better to disable the previous form's submit:

<form action="" method="post" name="form1">
  <input type="submit" name="submit"<?php if (isset($_POST['submit'])) { echo ' disabled="disabled"'; } ?>>
</form>
<?php if (isset($_POST['submit'])) { ?>
<form action="" method="post" name="form2">
  <input type="submit" name="submit">
</form>
<?php } ?>
