If two facebook pixels are placed, will only the first code be determined?

Question

Facebook

Tell me, if two pixels are placed, will Facebook determine only the first pixel that hits, and the second one will skip?
or will 2 scripts with different id be in action?

Answer 1

on an empty stomach only one pie
, but two accounts live together quite well, it is not clear only when it is needed

Answer 2

Properly install Pixel this way

<!-- Facebook Pixel Code -->
<script>
  !function(f,b,e,v,n,t,s)
  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
  n.queue=[];t=b.createElement(e);t.async=!0;
  t.src=v;s=b.getElementsByTagName(e)[0];
  s.parentNode.insertBefore(t,s)}(window, document,'script',
  'https://connect.facebook.net/en_US/fbevents.js');
  fbq('init', 'ИД ПЕРВЫЙ');
  fbq('init', 'ИД ВТОРОЙ');
  fbq('track', 'PageView');
</script>
